What is the Least Common Multiple of 101 and 118?

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 118 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 118, than apply into the LCM equation.

GCF(101,118) = 1
LCM(101,118) = ( 101 × 118) / 1
LCM(101,118) = 11918 / 1
LCM(101,118) = 11918

Least Common Multiple (LCM) of 101 and 118 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 101 and 118. First we will calculate the prime factors of 101 and 118.

Prime Factorization of 101

Prime Factorization of 118

Now multiplying the highest exponent prime factors to calculate the LCM of 101 and 118.

LCM(101,118) = 101¹ × 2¹ × 59¹
LCM(101,118) = 11918
