15 of them.
The factor tree of 225 is: 15, 15 3, 5, 3, 5 225 75,3 25,3,3 5,5,3,3
15
The greatest common factor of 45 and 225 is 15.The GCF is: 45
The GCF is 15.
(11w - 15)(11w - 15)
The answer is 15
5.
It is: 15
You can take 225 to 15 and 15. Then take 15 to 3 and 5. So, you have 3, 3, 5, 5.
The factor pairs of 225 are 1 x 225, 3 x 75, 5 x 45, 9 x 25, and 15 x 15
