What is the Least Common Multiple of 9020 and 9030?

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 9020 and 9030 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 9020 and 9030, than apply into the LCM equation.

GCF(9020,9030) = 10
LCM(9020,9030) = ( 9020 × 9030) / 10
LCM(9020,9030) = 81450600 / 10
LCM(9020,9030) = 8145060

Least Common Multiple (LCM) of 9020 and 9030 with Primes
