Lets's calculate LCM of 47,89,15

Given numbers has no common factors except 1. So, there LCM is their product i.e 62745

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/62745

Therefore, the GCF of Fractions 85/47,54/89,76/15 is 1/62745

Least Common Multiple of 47,89,15 with GCF Formula

Least Common Multiple of 47,89,15 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 47,89,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(47,89,15) = 1

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

GCF(47,89,15) x common factors =1 x 1 = 1

LCM(47,89,15) = ( 47 × 89 × 15 ) / 1

LCM(47,89,15) = 62745 / 1

LCM(47,89,15) = 62745
