Lets's calculate LCM of 21,443,421

LCM of Fractions 21/997,443/247,421/530 is 3916563

Given numbers has no common factors except 1. So, there LCM is their product i.e 3916563

Least Common Multiple of 21,443,421 with GCF Formula

Least Common Multiple of 21,443,421 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 21,443,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,443,421) = 1

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

GCF(21,443,421) x common factors =1 x 1 = 1

LCM(21,443,421) = ( 21 × 443 × 421 ) / 1

LCM(21,443,421) = 3916563 / 1

LCM(21,443,421) = 3916563


Lets's calculate GCF of 997,247,530

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3916563/1

Therefore the LCM of Fractions 21/997,443/247,421/530 is 3916563
