What is the Least Common Multiple of 200 and 211?

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 200 and 211 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 200 and 211, than apply into the LCM equation.

GCF(200,211) = 1
LCM(200,211) = ( 200 × 211) / 1
LCM(200,211) = 42200 / 1
LCM(200,211) = 42200

Least Common Multiple (LCM) of 200 and 211 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 200 and 211. First we will calculate the prime factors of 200 and 211.

Prime Factorization of 200

Prime Factorization of 211

Now multiplying the highest exponent prime factors to calculate the LCM of 200 and 211.

LCM(200,211) = 2³ × 5² × 211¹
LCM(200,211) = 42200
