The least common denominator for 7, 8, and 10 is 280.
Using the exponential method:
7 = 71
8 = 2 x 2 x 2 = 23
10 = 21 x 51
and the product of the largest exponential of each prime is
23 x 51 x 71 = 8 x 5 x 7 = 280
It is: 420
least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
