What is the Least Common Multiple of 30000 and 30005?

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 30005 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 30005, than apply into the LCM equation.

GCF(30000,30005) = 5
LCM(30000,30005) = ( 30000 × 30005) / 5
LCM(30000,30005) = 900150000 / 5
LCM(30000,30005) = 180030000

Least Common Multiple (LCM) of 30000 and 30005 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 30000 and 30005. First we will calculate the prime factors of 30000 and 30005.

Prime Factorization of 30000

Prime Factorization of 30005

Now multiplying the highest exponent prime factors to calculate the LCM of 30000 and 30005.

LCM(30000,30005) = 2⁴ × 3¹ × 5⁴ × 17¹ × 353¹
LCM(30000,30005) = 180030000
