What is the Least Common Multiple of 601 and 605?

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 601 and 605 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 601 and 605, than apply into the LCM equation.

GCF(601,605) = 1
LCM(601,605) = ( 601 × 605) / 1
LCM(601,605) = 363605 / 1
LCM(601,605) = 363605

Least Common Multiple (LCM) of 601 and 605 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 601 and 605. First we will calculate the prime factors of 601 and 605.

Prime Factorization of 601

Prime Factorization of 605

Now multiplying the highest exponent prime factors to calculate the LCM of 601 and 605.

LCM(601,605) = 601¹ × 5¹ × 11²
LCM(601,605) = 363605
