What is the Least Common Multiple of 10070 and 10075?

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 10070 and 10075 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10070 and 10075, than apply into the LCM equation.

GCF(10070,10075) = 5
LCM(10070,10075) = ( 10070 × 10075) / 5
LCM(10070,10075) = 101455250 / 5
LCM(10070,10075) = 20291050

Least Common Multiple (LCM) of 10070 and 10075 with Primes
