What is the Least Common Multiple of 10030 and 10045?

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 10030 and 10045 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10030 and 10045, than apply into the LCM equation.

GCF(10030,10045) = 5
LCM(10030,10045) = ( 10030 × 10045) / 5
LCM(10030,10045) = 100751350 / 5
LCM(10030,10045) = 20150270

Least Common Multiple (LCM) of 10030 and 10045 with Primes
