Lets's calculate LCM of 72,11,71,13

Given numbers has no common factors except 1. So, there LCM is their product i.e 731016

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/731016

Therefore, the GCF of Fractions 49/72,63/11,66/71,13/13 is 1/731016

Least Common Multiple of 72,11,71,13 with GCF Formula

Least Common Multiple of 72,11,71,13 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 72,11,71,13 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,11,71,13) = 1

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

GCF(72,11,71,13) x common factors =1 x 1 = 1

LCM(72,11,71,13) = ( 72 × 11 × 71 × 13 ) / 1

LCM(72,11,71,13) = 731016 / 1

LCM(72,11,71,13) = 731016
