What is the Least Common Multiple of 30000 and 30008?

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 30000 and 30008 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 30000 and 30008, than apply into the LCM equation.

GCF(30000,30008) = 8
LCM(30000,30008) = ( 30000 × 30008) / 8
LCM(30000,30008) = 900240000 / 8
LCM(30000,30008) = 112530000

Least Common Multiple (LCM) of 30000 and 30008 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 30000 and 30008. First we will calculate the prime factors of 30000 and 30008.

Prime Factorization of 30000

Prime Factorization of 30008

Now multiplying the highest exponent prime factors to calculate the LCM of 30000 and 30008.

LCM(30000,30008) = 2⁴ × 3¹ × 5⁴ × 11² × 31¹
LCM(30000,30008) = 112530000
