Lets's calculate LCM of 73,47,71,90

Given numbers has no common factors except 1. So, there LCM is their product i.e 21924090

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21924090

Therefore, the GCF of Fractions 40/73,35/47,81/71,63/90 is 1/21924090

Least Common Multiple of 73,47,71,90 with GCF Formula

Least Common Multiple of 73,47,71,90 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 73,47,71,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(73,47,71,90) = 1

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

GCF(73,47,71,90) x common factors =1 x 1 = 1

LCM(73,47,71,90) = ( 73 × 47 × 71 × 90 ) / 1

LCM(73,47,71,90) = 21924090 / 1

LCM(73,47,71,90) = 21924090
