No matter what you use, you still need at least two numbers to find a GCF.

An interesting trick is to subtract the two numbers, as follows: For example, the GCF of 14 and 10 is the same as the GCF of 10 and 4, where 4 is the result of the subtraction. Instead of subtracting several times, you can also get the remainder of a division: 10 divided by 4 gives a remainder of 2.
The GCF is 2.
The GCF of 10 and 15 is 5.

The prime factorization of 10 is 2 x 5. You need another number to find a GCF or LCM.

It's the same as the gcf of 10 and 5 - where 5 is the remainder of the division of 95 by 10.
