LCM and GCF of 10 and 25

The GCF or greatest common factor is the largest positive integer that will divide into each number evenly.

For example, the greatest common factor of 2 and 4 would be 2.

There are several different names for the GCF ( greatest common factor)

GCD Greatest Common Denominator

HCF Highest Common Factor

GCD Greatest Common Divisor

I like to use a factor tree to find the LCM and the GCF

Once you find all of the prime factors of a number, to find the GCF you multiply all of the factors, but multiply duplicates in each number only once.

In order to calculate the LCM you look for factors in each number and multiply these common positive integers together.
