questioned by administrator @ in Mathematics viewed by 135 People


What is the greatest common factor (gcf) of 15 and 64

Answered by administrator @



The GCF is the product of the shared primes of the numbers prime factorization.

15=3*5 and 64=2*2*2*2*2*2

So there are no shared primes thus the greatest common factor is just one.
