Lets's calculate LCM of 65,22,57,521

Given numbers has no common factors except 1. So, there LCM is their product i.e 42466710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42466710

Therefore, the GCF of Fractions 29/65,90/22,21/57,49/521 is 1/42466710

Least Common Multiple of 65,22,57,521 with GCF Formula

Least Common Multiple of 65,22,57,521 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 65,22,57,521 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(65,22,57,521) = 1

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

GCF(65,22,57,521) x common factors =1 x 1 = 1

LCM(65,22,57,521) = ( 65 × 22 × 57 × 521 ) / 1

LCM(65,22,57,521) = 42466710 / 1

LCM(65,22,57,521) = 42466710
