What is the Least Common Multiple of 13010 and 13020?

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 13010 and 13020 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 13010 and 13020, than apply into the LCM equation.

GCF(13010,13020) = 10
LCM(13010,13020) = ( 13010 × 13020) / 10
LCM(13010,13020) = 169390200 / 10
LCM(13010,13020) = 16939020

Least Common Multiple (LCM) of 13010 and 13020 with Primes
