What is the Least Common Multiple of 21050 and 21061?

Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.

Least Common Multiple of 21050 and 21061 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 21050 and 21061, than apply into the LCM equation.

GCF(21050,21061) = 1
LCM(21050,21061) = ( 21050 × 21061) / 1
LCM(21050,21061) = 443334050 / 1
LCM(21050,21061) = 443334050

Least Common Multiple (LCM) of 21050 and 21061 with Primes
