Find the GCF of 5 and 12
GCF is the greatest common factor that divides the two numbers without leaving any remainder.
Answer: The GCF of 5 and 12 is 1
Let us see how to find the GCF of 5 and 12
Calculating GCF can be done in several ways such as:
- Listing Factors
- Long division
Method 1: Listing factors:
Let's list down the factors of 5 and 12
Factors of 5 : 1,5
Factors of 12 : 1,2,3,4,6,12
Common factor of 5 and 12 = 1
Hence, GCF(5,12) = 1
Method 2: Long Division:
- Divide the larger number by the smaller number.
- Now divide the divisor by the remainder.
- Repeat the process of dividing the preceding number by the remainder last until 0 zero is obtained as remainder.
- The last divisor is called GCF
