What is the Least Common Multiple of 11001 and 11020?

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 11001 and 11020 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 11001 and 11020, than apply into the LCM equation.

GCF(11001,11020) = 19
LCM(11001,11020) = ( 11001 × 11020) / 19
LCM(11001,11020) = 121231020 / 19
LCM(11001,11020) = 6380580

Least Common Multiple (LCM) of 11001 and 11020 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 11001 and 11020. First we will calculate the prime factors of 11001 and 11020.

Prime Factorization of 11001
