What is the Least Common Multiple of 2011 and 2016?

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 2011 and 2016 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2011 and 2016, than apply into the LCM equation.

GCF(2011,2016) = 1
LCM(2011,2016) = ( 2011 × 2016) / 1
LCM(2011,2016) = 4054176 / 1
LCM(2011,2016) = 4054176

Least Common Multiple (LCM) of 2011 and 2016 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 2011 and 2016. First we will calculate the prime factors of 2011 and 2016.

Prime Factorization of 2011

Prime Factorization of 2016

Now multiplying the highest exponent prime factors to calculate the LCM of 2011 and 2016.

LCM(2011,2016) = 2011¹ × 2⁵ × 3² × 7¹
LCM(2011,2016) = 4054176
