# Least Common Multiple of 32 and 60

Least common multiple (LCM) of 32 and 60 is **480**.

LCM(32,60) = 480

*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 32 and 60 with GCF Formula

The formula of **LCM** is LCM(a,b) = ( a × b) / GCF(a,b).

We need to calculate greatest common factor 32 and 60, than apply into the LCM equation.

GCF(32,60) = 4

LCM(32,60) = ( 32 × 60) / 4

LCM(32,60) = 1920 / 4

LCM(32,60) = 480

## Least Common Multiple (LCM) of 32 and 60 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 32 and 60. First we will calculate the **prime factors of 32 and 60**.

### Prime Factorization of 32

Prime factors of 32 are 2. Prime factorization of **32** in exponential form is:

32 = 2^{5}

### Prime Factorization of 60

Prime factors of 60 are 2, 3, 5. Prime factorization of **60** in exponential form is:

60 = 2^{2} × 3^{1} × 5^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 32 and 60**.

LCM(32,60) = 2^{5} × 3^{1} × 5^{1}

LCM(32,60) = 480
