What is the Least Common Multiple of 17001 and 17005?

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 17001 and 17005 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 17001 and 17005, than apply into the LCM equation.

GCF(17001,17005) = 1
LCM(17001,17005) = ( 17001 × 17005) / 1
LCM(17001,17005) = 289102005 / 1
LCM(17001,17005) = 289102005

Least Common Multiple (LCM) of 17001 and 17005 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 17001 and 17005. First we will calculate the prime factors of 17001 and 17005.

Prime Factorization of 17001
