How to find the gcf of 8 and 10?
Method 1 - Listing Factors
To find the gcf of 8 and 10, we first need to find the factors of 8 and 10 and then choose the greatest common factor that are dividable by both 8 and 10.
Factors of 8 = 1, 2, 4, 8
Factors of 10 = 1, 2, 5, 10
The greatest common factor of 8 and 10 is 2, because 2 is the largest number that is divisible by both numbers.
Method 2 - Prime Factorization
Another method to find the greatest common factor of 8 and 10 is by using the prime factorization method.
To use prime factorization, we first need to find the prime factors of 8 and 10, and then get the GCF by multiplying all the common prime factors from the two sets.
Prime factorization of 8 = 2 x 2 x 2
Prime factorization of 10 = 2 x 5
Common prime factors = 2 = 2
