For example, if you want to find the least common multiple of 120 and 756:

Press Math and select NUM at the top with the arrow keys. Scroll down and choose the option that says gcd(. (This stands for greatest common denominator.) Then type the first number, followed by a comma, followed by the second number. Put in an ending parenthesis (If you don't, it will still work, but this is good practice for when you get to more complex problems.) You should see:

gcd(120,756)

Press ENTER. In this case, the answer will be 12.

You can find the Greatest Common Factor between two numbers by using the gcd function (which is found by pressing MATH and then choosing NUM and the top and scrolling down).

For example, to find the GCF of 50 and 78, type:

gcd(50,78)

Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
