Factors:
22 : 1 2 11 22
33 : 1 3 11 33
Both have the GCF of 11. By removing 11 from both numbers you end up with:
22 = 2 * 11
33 = 3 * 11
Now replace the values on the right of the equals sign into the original equation:
(2 * 11) + ( 3 * 11)
The distributive property allows us to remove the common values and rewrite as:
11(2 + 3)
This gives:
11(5)
