What is the Least Common Multiple of 1002 and 1014?

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 1002 and 1014 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1002 and 1014, than apply into the LCM equation.

GCF(1002,1014) = 6
LCM(1002,1014) = ( 1002 × 1014) / 6
LCM(1002,1014) = 1016028 / 6
LCM(1002,1014) = 169338

Least Common Multiple (LCM) of 1002 and 1014 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 1002 and 1014. First we will calculate the prime factors of 1002 and 1014.

Prime Factorization of 1002
