A factor tree of 1575: 1575 / \ 5 325 / \ 5 65 / \ 5 13 Answer: 5*5*5*13 or 13*53
You have just written it "in numbers."
You need two or more numbers to find common factors.ex. "What are the common factors of 1575 and 1780?"
315 over 1575 in lowest terms = 1/5
(1575-1250)/original figure, 1575... x100 = 20.63% decrease
7875
As a product of its prime factors: 3*3*5*5*7 = 1575

The answer is 1575*5 = 7875
1575 = 32 x 52 x 7
1575 = 3 * 3 * 5 * 5 * 73 x 3 x 5 x 5 x 7 = 1575
