The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share items equally, to group or arrange items, and schedule events. In this topic, we will learn about the GCF of 48 and 64.
The greatest common factor of 48 and 64 is 16. The largest divisor of two or more numbers is called the GCF of the numbers. 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.
To find the GCF of 48 and 64, a few methods are described below -
Steps to find the GCF of 48 and 64 using the listing of factors
Step 1: Firstly, list the factors of each number
Factors of 48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.
Factors of 64 = 1, 2, 4, 8, 16, 32, 64.
Step 2: Now, identify the common factors of them Common factors of 48 and 64: 1, 2, 4, 8, 16.
Step 3: Choose the largest factor
The largest factor that both numbers have is 16.
The GCF of 48 and 64 is 16.
To find the GCF of 48 and 64 using the Prime Factorization Method, follow these steps:
Step 1: Find the prime factors of each number
Prime Factors of 48: 48 = 2 x 2 x 2 x 2 x 3 = 2^4 x 3
Prime Factors of 64: 64 = 2 x 2 x 2 x 2 x 2 x 2 = 2^6
Step 2: Now, identify the common prime factors
The common prime factors are: 2 x 2 x 2 x 2 = 2^4
Step 3: Multiply the common prime factors 2^4 = 16.
The Greatest Common Factor of 48 and 64 is 16.
Find the GCF of 48 and 64 using the division method or Euclidean Algorithm Method. Follow these steps:
Step 1: First, divide the larger number by the smaller number
Here, divide 64 by 48 64 ÷ 48 = 1 (quotient),
The remainder is calculated as 64 − (48×1) = 16
The remainder is 16, not zero, so continue the process
Step 2: Now divide the previous divisor (48) by the previous remainder (16)
Divide 48 by 16 48 ÷ 16 = 3 (quotient), remainder = 48 − (16×3) = 0
The remainder is zero, the divisor will become the GCF.
The GCF of 48 and 64 is 16.
Finding GCF of 48 and 64 looks simple, but students often make mistakes while calculating the GCF. Here are some common mistakes to be avoided by the students.
A gardener has 48 rose plants and 64 sunflower plants. She wants to group them into equal sets, with the largest number of plants in each group. How many plants will be in each group?
We should find the GCF of 48 and 64 GCF of 48 and 64 2^4 = 16.
There are 16 equal groups 48 ÷ 16 = 3 64 ÷ 16 = 4
There will be 16 groups, and each group gets 3 rose plants and 4 sunflower plants.
As the GCF of 48 and 64 is 16, the gardener can make 16 groups. Now divide 48 and 64 by 16. Each group gets 3 rose plants and 4 sunflower plants.
A bakery has 48 chocolate cupcakes and 64 vanilla cupcakes. They want to arrange them in trays with the same number of cupcakes on each tray, using the largest possible number of cupcakes per tray. How many cupcakes will be on each tray?
GCF of 48 and 64 2^4 = 16.
So each tray will have 16 cupcakes.
There are 48 chocolate and 64 vanilla cupcakes. To find the total number of cupcakes on each tray, we should find the GCF of 48 and 64. There will be 16 cupcakes on each tray.
A ribbon factory has 48 meters of green ribbon and 64 meters of blue ribbon. They want to cut both ribbons 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 48 and 64
The GCF of 48 and 64 2^4 = 16.
The ribbon is 16 meters long.
For calculating the longest length of the ribbon first, we need to calculate the GCF of 48 and 64, which is 16. The length of each piece of the ribbon will be 16 meters.
A carpenter has two wooden planks, one 48 cm long and the other 64 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 48 and 64 2^4 = 16.
The longest length of each piece is 16 cm.
To find the longest length of each piece of the two wooden planks, 48 cm and 64 cm, respectively. We have to find the GCF of 48 and 64, which is 16 cm. The longest length of each piece is 16 cm.
If the GCF of 48 and ‘b’ is 16, and the LCM is 192. Find ‘b’.
The value of ‘b’ is 64.
GCF x LCM = product of the numbers 16 × 192 = 48 × b
3072 = 48b
b = 3072 ÷ 48 = 64
