What is the Least Common Multiple of 80001 and 80010?

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 80010 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 80010, than apply into the LCM equation.

GCF(80001,80010) = 9
LCM(80001,80010) = ( 80001 × 80010) / 9
LCM(80001,80010) = 6400880010 / 9
LCM(80001,80010) = 711208890

Least Common Multiple (LCM) of 80001 and 80010 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 80001 and 80010. First we will calculate the prime factors of 80001 and 80010.
