What is the Least Common Multiple of 201 and 212?

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 201 and 212 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 201 and 212, than apply into the LCM equation.

GCF(201,212) = 1
LCM(201,212) = ( 201 × 212) / 1
LCM(201,212) = 42612 / 1
LCM(201,212) = 42612

Least Common Multiple (LCM) of 201 and 212 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 201 and 212. First we will calculate the prime factors of 201 and 212.

Prime Factorization of 201

Prime Factorization of 212

Now multiplying the highest exponent prime factors to calculate the LCM of 201 and 212.

LCM(201,212) = 3¹ × 67¹ × 2² × 53¹
LCM(201,212) = 42612
