Answer 2

answer

A short cut to find the H.C.F of two or more fractions is: (HCF of the numerators)/(L.C.M of denominators)

Thus, the Greatest common factor of the numerators in this case is, 1.

Briefing it- 3, 7, 8 have one as the common factor. 3 and 7 being prime numbers have 1 as the common factor. 8 has factors as 2 x 2 x 2 x 1.

So all the three have only 1 has the highest common factor. Hence, H.C.F of numerators is 1.

Coming to finding the L.C.M of denominators.

The L.C.M of 5, 8, 15 is 5 x 3 x 2 x 2 x 2 x 1 which is 120.

The final answer is 1/120.
