The least common factor of any set of numbers is 1.
gcf(15, 13, 25) = 1.
13
The GCF is 1.
One is the only common factor of 8 9 13 and 15?
The GCF is 1.
1 is a common factor of 11, 12, 13, 14 and 15.
The least common factor of any set of integers is 1.
1
The GCF is 1.
They only have a common factor of one(1), so the product of 13 & 15 is the same as the LCM. 195
13 is prime, so it's factors are 1 & 13. 15 = 1 * 3 * 5, so 1 is the only common factor.
