What is the Least Common Multiple of 8001 and 8016?

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 8001 and 8016 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 8001 and 8016, than apply into the LCM equation.

GCF(8001,8016) = 3
LCM(8001,8016) = ( 8001 × 8016) / 3
LCM(8001,8016) = 64136016 / 3
LCM(8001,8016) = 21378672

Least Common Multiple (LCM) of 8001 and 8016 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 8001 and 8016. First we will calculate the prime factors of 8001 and 8016.

Prime Factorization of 8001

Prime Factorization of 8016

Now multiplying the highest exponent prime factors to calculate the LCM of 8001 and 8016.

LCM(8001,8016) = 3² × 7¹ × 127¹ × 2⁴ × 167¹
LCM(8001,8016) = 21378672
