What is the Least Common Multiple of 3021 and 3030?

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 3021 and 3030 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 3021 and 3030, than apply into the LCM equation.

GCF(3021,3030) = 3
LCM(3021,3030) = ( 3021 × 3030) / 3
LCM(3021,3030) = 9153630 / 3
LCM(3021,3030) = 3051210
