What is the Least Common Multiple of 6 and 8?

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 (LCM) of 6 and 8 is 24.

LCM(6,8) = 24

Least Common Multiple of 6 and 8 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 6 and 8, than apply into the LCM equation.

GCF(6,8) = 2
LCM(6,8) = ( 6 × 8) / 2
LCM(6,8) = 48 / 2
LCM(6,8) = 24

Least Common Multiple (LCM) of 6 and 8 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 6 and 8. First we will calculate the prime factors of 6 and 8.

Prime Factorization of 6

Prime factors of 6 are 2, 3. Prime factorization of 6 in exponential form is:

6 = 21 × 31

Prime Factorization of 8

Prime factors of 8 are 2. Prime factorization of 8 in exponential form is:

8 = 23

Now multiplying the highest exponent prime factors to calculate the LCM of 6 and 8.

LCM(6,8) = 23 × 31
LCM(6,8) = 24
