A factor tree of 1575: 1575 / \ 5 325 / \ 5 65 / \ 5 13 Answer: 5*5*5*13 or 13*53
Since 35 is a factor of 1575, it is automatically the GCF.
Since 315 is a factor of 1575, it is automatically the GCF of this problem.
1,3,5,7,9,15,21,25,35,45,63,75,105,175,225,315,525,1575
As a product of its prime factors: 3*3*5*5*7 = 1575
105
The GCF is 63.
Factorization: 3*3*5*5*7
The factor pairs of 1575 are 1 x 1575, 3 x 525, 5 x 315, 7 x 225, 9 x 175, 15 x 105, 21 x 75, 25 x 63, and 35 x 45.
1250 breaks down to 250 and 5. 250 breaks down to 25 and 10. 25 breaks down to 5 and 5... 10 breaks down to 5 and 2. so the branches of your tree should have 5, 5, 5, 5, and 2 on the ends.
The GCF is 105.
The GCF of 1225 and 1575 is 175
