Lets's calculate LCM of 90,97,41

Given numbers has no common factors except 1. So, there LCM is their product i.e 357930

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/357930

Therefore, the GCF of Fractions 75/90,21/97,520/41 is 1/357930

Least Common Multiple of 90,97,41 with GCF Formula

Least Common Multiple of 90,97,41 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 90,97,41 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,97,41) = 1

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

GCF(90,97,41) x common factors =1 x 1 = 1

LCM(90,97,41) = ( 90 × 97 × 41 ) / 1

LCM(90,97,41) = 357930 / 1

LCM(90,97,41) = 357930
