What is the Least Common Multiple of 101 and 108?

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 101 and 108 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 101 and 108, than apply into the LCM equation.

GCF(101,108) = 1
LCM(101,108) = ( 101 × 108) / 1
LCM(101,108) = 10908 / 1
LCM(101,108) = 10908

Least Common Multiple (LCM) of 101 and 108 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 101 and 108. First we will calculate the prime factors of 101 and 108.

Prime Factorization of 101

Prime Factorization of 108

Now multiplying the highest exponent prime factors to calculate the LCM of 101 and 108.

LCM(101,108) = 101¹ × 2² × 3³
LCM(101,108) = 10908
