Lets's calculate LCM of 63,85,92

Given numbers has no common factors except 1. So, there LCM is their product i.e 492660

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/492660

Therefore, the GCF of Fractions 42/63,20/85,372/92 is 2/492660

Least Common Multiple of 63,85,92 with GCF Formula

Least Common Multiple of 63,85,92 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 63,85,92 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,85,92) = 1

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

GCF(63,85,92) x common factors =1 x 1 = 1

LCM(63,85,92) = ( 63 × 85 × 92 ) / 1

LCM(63,85,92) = 492660 / 1

LCM(63,85,92) = 492660
