GCF of 12 and 52
The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share items equally, group or arrange items, and schedule events. In this topic, we will learn about the GCF of 12 and 52.
What is the GCF of 12 and 52?
The greatest common factor of 12 and 52 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 52?
To find the GCF of 12 and 52, a few methods are described below
- Listing Factors
- Prime Factorization
- Long Division Method / by Euclidean Algorithm
GCF of 12 and 52 by Using Listing of Factors
Steps to find the GCF of 12 and 52 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 52 = 1, 2, 4, 13, 26, 52.
Step 2: Now, identify the common factors of them Common factors of 12 and 52: 1, 2, 4.
Step 3: Choose the largest factor The largest factor that both numbers have is 4.
The GCF of 12 and 52 is 4.
GCF of 12 and 52 Using Prime Factorization
To find the GCF of 12 and 52 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 52: 52 = 2 x 2 x 13 = 2² x 13
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 52 is 4.
GCF of 12 and 52 Using Division Method or Euclidean Algorithm Method
Find the GCF of 12 and 52 using the division method or Euclidean Algorithm Method. Follow these steps:
Step 1: First, divide the larger number by the smaller number Here, divide 52 by 12 52 ÷ 12 = 4 (quotient), The remainder is calculated as 52 − (12×4) = 4 The remainder is 4, not zero, so continue the process
Step 2: Now divide the previous divisor (12) by the previous remainder (4) Divide 12 by 4 12 ÷ 4 = 3 (quotient), remainder = 12 − (4×3) = 0 The remainder is zero, the divisor will become the GCF.
The GCF of 12 and 52 is 4.
Common Mistakes and How to Avoid Them in GCF of 12 and 52
Finding the GCF of 12 and 52 looks simple, but students often make mistakes while calculating the GCF. Here are some common mistakes to be avoided by students.
Mistake 1
Listing Incorrect Factors
Students may sometimes list incorrect factors.
For example, while listing factors of 12, students may mention 5 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 factors with 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 because 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 52 Examples
Problem 1
An artist has 12 paintbrushes and 52 paint tubes. She wants to group them into equal sets, with the largest number of items in each group. How many items will be in each group?
We should find the GCF of 12 and 52 GCF of 12 and 52 2² = 4.
There are 4 equal groups 12 ÷ 4 = 3 52 ÷ 4 = 13
There will be 4 groups, and each group gets 3 paintbrushes and 13 paint tubes.
Explanation
As the GCF of 12 and 52 is 4, the artist can make 4 groups.
Now divide 12 and 52 by 4.
Each group gets 3 paintbrushes and 13 paint tubes.
Problem 2
A gardener has 12 pots of flowers and 52 packets of seeds. They want to arrange them in rows with the same number of items in each row, using the largest possible number of items per row. How many items will be in each row?
GCF of 12 and 52 2² = 4.
So each row will have 4 items.
Explanation
There are 12 pots of flowers and 52 packets of seeds.
To find the total number of items in each row, we should find the GCF of 12 and 52.
There will be 4 items in each row.
Problem 3
A tailor has 12 meters of red fabric and 52 meters of blue fabric. She wants to cut both fabrics into pieces of equal length, using the longest possible length. What should be the length of each piece?
For calculating the longest equal length, we have to calculate the GCF of 12 and 52
The GCF of 12 and 52 2² = 4.
Each piece of fabric is 4 meters long.
Explanation
For calculating the longest length of the fabric, first we need to calculate the GCF of 12 and 52, which is 4.
The length of each piece of fabric will be 4 meters.
Problem 4
A carpenter has two wooden planks, one 12 cm long and the other 52 cm long. He wants to cut them into the longest possible equal pieces, without any wood left over. What should be the length of each piece?
The carpenter needs the longest piece of wood GCF of 12 and 52 2² = 4.
The longest length of each piece is 4 cm.
Explanation
To find the longest length of each piece of the two wooden planks, 12 cm and 52 cm, respectively.
We have to find the GCF of 12 and 52, which is 4 cm.
The longest length of each piece is 4 cm.
Problem 5
If the GCF of 12 and ‘b’ is 4, and the LCM is 156, find ‘b’.
The value of ‘b’ is 52.
Explanation
GCF x LCM = product of the numbers 4 × 156 = 12 × b
624 = 12b
b = 624 ÷ 12 = 52
