Lets's calculate LCM of 32,71,90

2 32, 71, 90
16, 71, 45

∴ So the LCM of the given numbers is 2 x 16 x 71 x 45 = 102240

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/102240

Therefore, the GCF of Fractions 72/32,491/71,900/90 is 1/102240

Least Common Multiple of 32,71,90 with GCF Formula

Least Common Multiple of 32,71,90 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 32,71,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(32,71,90) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(32,71,90) x common factors =1 x 2 = 2

LCM(32,71,90) = ( 32 × 71 × 90 ) / 2

LCM(32,71,90) = 204480 / 2

LCM(32,71,90) = 102240
