What is the Least Common Multiple of 10015 and 10030?

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 10015 and 10030 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10015 and 10030, than apply into the LCM equation.

GCF(10015,10030) = 5
LCM(10015,10030) = ( 10015 × 10030) / 5
LCM(10015,10030) = 100450450 / 5
LCM(10015,10030) = 20090090

Least Common Multiple (LCM) of 10015 and 10030 with Primes
