What is the Least Common Multiple of 30100 and 30109?

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 30100 and 30109 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 30100 and 30109, than apply into the LCM equation.

GCF(30100,30109) = 1
LCM(30100,30109) = ( 30100 × 30109) / 1
LCM(30100,30109) = 906280900 / 1
LCM(30100,30109) = 906280900

Least Common Multiple (LCM) of 30100 and 30109 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 30100 and 30109. First we will calculate the prime factors of 30100 and 30109.
