Answer: GCF of 32 and 40 is 8
Two methods to find the GCF of 32 and 40 are explained below.
Methods to find GCF of 32 and 40
- Listing the common factors method
- Long division Method
Method1: Listing the Common Factors
Common Factors of 32 and 40: 2, 4, 8
The greatest common factor is 8
GCF of 32 and 40 is 8
Method2: Long Division
- Step 1: Larger number(40) is taken as dividend and the smaller(32) as the divisor and then the division is performed.
- Step 2: Make the remainder of the above step as the divisor and the divisor of the above step as the dividend and perform the long division again.
- Step 3: Continue till you get remainder as 0
The above two methods yeild the same answer.
