Lets's calculate LCM of 79,15,59

Given numbers has no common factors except 1. So, there LCM is their product i.e 69915

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/69915

Therefore, the GCF of Fractions 720/79,786/15,812/59 is 2/69915

Least Common Multiple of 79,15,59 with GCF Formula

Least Common Multiple of 79,15,59 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 79,15,59 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(79,15,59) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(79,15,59) x common factors =1 x 1 = 1

LCM(79,15,59) = ( 79 × 15 × 59 ) / 1

LCM(79,15,59) = 69915 / 1

LCM(79,15,59) = 69915
