Least Common Multiple of 3 and 24

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 3 and 24 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 3 and 24, than apply into the LCM equation.

GCF(3,24) = 3
LCM(3,24) = ( 3 × 24) / 3
LCM(3,24) = 72 / 3
LCM(3,24) = 24

Least Common Multiple (LCM) of 3 and 24 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 3 and 24. First we will calculate the prime factors of 3 and 24.

Prime Factorization of 3

Prime Factorization of 24

Now multiplying the highest exponent prime factors to calculate the LCM of 3 and 24.

LCM(3,24) = 3¹ × 2³
LCM(3,24) = 24
