What is the Least Common Multiple of 22015 and 22028?

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 22015 and 22028 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 22015 and 22028, than apply into the LCM equation.

GCF(22015,22028) = 1
LCM(22015,22028) = ( 22015 × 22028) / 1
LCM(22015,22028) = 484946420 / 1
LCM(22015,22028) = 484946420

Least Common Multiple (LCM) of 22015 and 22028 with Primes
