What is the Least Common Multiple of 80001 and 80017?

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 80001 and 80017 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 80001 and 80017, than apply into the LCM equation.

GCF(80001,80017) = 1
LCM(80001,80017) = ( 80001 × 80017) / 1
LCM(80001,80017) = 6401440017 / 1
LCM(80001,80017) = 6401440017

Least Common Multiple (LCM) of 80001 and 80017 with Primes
