What is the Least Common Multiple of 301 and 305?

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 301 and 305 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 301 and 305, than apply into the LCM equation.

GCF(301,305) = 1
LCM(301,305) = ( 301 × 305) / 1
LCM(301,305) = 91805 / 1
LCM(301,305) = 91805

Least Common Multiple (LCM) of 301 and 305 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 301 and 305. First we will calculate the prime factors of 301 and 305.

Prime Factorization of 301

Prime Factorization of 305

Now multiplying the highest exponent prime factors to calculate the LCM of 301 and 305.

LCM(301,305) = 7¹ × 43¹ × 5¹ × 61¹
LCM(301,305) = 91805
