75/175 = 42.857%
1225
It's the same as gcf(gcf(75, 100), 175). In other words, you can first use Euclid's algorithm to find the gcf of 75 and 100; then you can calculate the gcf of the result with 175. To help you get started, by Euclid's algorithm, the gcf of 75 and 100 is the same as the gcf of 75 and 25 (where 25 is the remnainder of the division of 100 / 75).
It is 25
The prime factorization of 175 is:5 X 5 X 75 x 5 x 75 x 5 x 7 = 1755 x 5 x 7 = 175
LCD of 75 and 60 is 1500.
