GCF of 12 and 44
The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share the items equally, to group or arrange items and schedule events. In this topic, we will learn about the GCF of 12 and 44.
What is the GCF of 12 and 44?
The greatest common factor of 12 and 44 is 4. The largest divisor of two or more numbers is called the GCF of the number. If two numbers are co-prime, they have no common factors other than 1, so their GCF is 1. The GCF of two numbers cannot be negative because divisors are always positive.
How to find the GCF of 12 and 44?
To find the GCF of 12 and 44, a few methods are described below:
- Listing Factors
- Prime Factorization
- Long Division Method or Euclidean Algorithm
GCF of 12 and 44 by Using Listing of Factors
Steps to find the GCF of 12 and 44 using the listing of factors:
Step 1: Firstly, list the factors of each number
Factors of 12 = 1, 2, 3, 4, 6, 12.
Factors of 44 = 1, 2, 4, 11, 22, 44.
Step 2: Now, identify the common factors of them Common factors of 12 and 44: 1, 2, 4.
Step 3: Choose the largest factor The largest factor that both numbers have is 4.
The GCF of 12 and 44 is 4.
GCF of 12 and 44 Using Prime Factorization
To find the GCF of 12 and 44 using the Prime Factorization Method, follow these steps:
Step 1: Find the prime factors of each number:
Prime Factors of 12: 12 = 2 x 2 x 3 = 2² x 3
Prime Factors of 44: 44 = 2 x 2 x 11 = 2² x 11
Step 2: Now, identify the common prime factors
The common prime factors are: 2 x 2 = 2²
Step 3: Multiply the common prime factors 2² = 4.
The Greatest Common Factor of 12 and 44 is 4.
GCF of 12 and 44 Using Division Method or Euclidean Algorithm Method
Find the GCF of 12 and 44 using the division method or Euclidean Algorithm Method. Follow these steps:
Step 1: First, divide the larger number by the smaller number.
Here, divide 44 by 12 44 ÷ 12 = 3 (quotient).
The remainder is calculated as 44 − (12×3) = 8
The remainder is 8, not zero, so continue the process
Step 2: Now divide the previous divisor (12) by the previous remainder (8)
Divide 12 by 8 12 ÷ 8 = 1 (quotient), remainder = 12 − (8×1) = 4
Step 3: Now divide the previous divisor (8) by the previous remainder (4)
Divide 8 by 4 8 ÷ 4 = 2 (quotient), remainder = 8 − (4×2) = 0
The remainder is zero, the divisor will become the GCF.
The GCF of 12 and 44 is 4.
Common Mistakes and How to Avoid Them in GCF of 12 and 44
Finding GCF of 12 and 44 looks simple, but students often make mistakes while calculating the GCF. Here are some common mistakes to be avoided by the students.
Mistake 1
Listing Incorrect Factors
Students may sometimes list incorrect factors.
For example, while listing factors of 12, students may mention 10, which is incorrect. To avoid this, students should carefully divide the number and list the factors correctly.
Mistake 2
Choosing the wrong common factor
Students may sometimes select the smallest common factor instead of the largest one. To avoid this confusion, students should list all the common factors and find the greatest one.
Mistake 3
Forgetting to include 1 as a factor
Sometimes students may forget 1 as a common factor of the numbers. However, it does not affect the GCF, but it indicates an incomplete understanding of the factors. Students should include 1 as a factor.
Mistake 4
Using Multiples instead of factors
Students confuse between factors and multiples. In that confusion, sometimes they may write multiples instead of factors. To avoid this confusion, students should know the definitions of multiples and factors clearly.
Mistake 5
Assuming GCF is always an even number
Students may assume that the GCF of two numbers will always be an even number. But it's not true that a GCF can also be an odd number. To avoid this, students should focus on common factors rather than focusing on even and odd numbers.
Greatest Common Factor of 12 and 44 Examples
Problem 1
A gardener has 12 apple trees and 44 orange trees. They want to plant them in rows with the same number of trees in each row, using the largest possible number of trees per row. How many trees will be in each row?
We should find the GCF of 12 and 44 GCF of 12 and 44 2² = 4 So each row will have 4 trees.
Explanation
There are 12 apple trees and 44 orange trees.
To find the total number of trees in each row, we should find the GCF of 12 and 44.
There will be 4 trees in each row.
Problem 2
A chef has 12 kilograms of flour and 44 kilograms of sugar. He wants to pack them into the longest possible bags of equal weight. What should be the weight of each bag?
For calculating the longest equal weight, we have to calculate the GCF of 12 and 44
The GCF of 12 and 44 2² = 4
The weight of each bag is 4 kilograms.
Explanation
For calculating the longest weight of the bags, first we need to calculate the GCF of 12 and 44, which is 4. The weight of each bag will be 4 kilograms.
Problem 3
A music teacher has two sets of instruments: 12 drums and 44 flutes. She wants to divide them into the largest possible number of groups, with an equal number of each type of instrument in each group. How many groups can she make?
We should find the GCF of 12 and 44 GCF of 12 and 44 2² = 4
There are 4 equal groups.
12 ÷ 4 = 3 4
4 ÷ 4 = 11
There will be 4 groups, and each group gets 3 drums and 11 flutes.
Explanation
As the GCF of 12 and 44 is 4, the music teacher can make 4 groups. Now divide 12 and 44 by 4. Each group gets 3 drums and 11 flutes.
Problem 4
A tailor has two rolls of fabric, one 12 meters long and the other 44 meters long. She wants to cut them into the longest possible pieces of equal length, without any fabric left over. What should be the length of each piece?
The tailor needs the longest piece of fabric GCF of 12 and 44 2² = 4 The longest length of each piece is 4 meters.
Explanation
To find the longest length of each piece of the two fabric rolls, 12 meters and 44 meters, respectively, we have to find the GCF of 12 and 44, which is 4 meters. The longest length of each piece is 4 meters.
Problem 5
If the GCF of 12 and ‘b’ is 4, and the LCM is 132, find ‘b’.
The value of ‘b’ is 44.
Explanation
GCF × LCM = product of the numbers 4 × 132 = 12 × b 528 = 12b b = 528 ÷ 12 = 44
