What is the Least Common Multiple of 10011 and 10020?

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 10011 and 10020 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10011 and 10020, than apply into the LCM equation.

GCF(10011,10020) = 3
LCM(10011,10020) = ( 10011 × 10020) / 3
LCM(10011,10020) = 100310220 / 3
LCM(10011,10020) = 33436740

Least Common Multiple (LCM) of 10011 and 10020 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 10011 and 10020. First we will calculate the prime factors of 10011 and 10020.
