# What is the Least Common Multiple of 48 and 52?

*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 48 and 52 is **624**.

LCM(48,52) = 624

## Least Common Multiple of 48 and 52 with GCF Formula

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

We need to calculate greatest common factor 48 and 52, than apply into the LCM equation.

GCF(48,52) = 4

LCM(48,52) = ( 48 × 52) / 4

LCM(48,52) = 2496 / 4

LCM(48,52) = 624

## Least Common Multiple (LCM) of 48 and 52 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 48 and 52. First we will calculate the **prime factors of 48 and 52**.

### Prime Factorization of 48

Prime factors of 48 are 2, 3. Prime factorization of **48** in exponential form is:

48 = 2^{4} × 3^{1}

### Prime Factorization of 52

Prime factors of 52 are 2, 13. Prime factorization of **52** in exponential form is:

52 = 2^{2} × 13^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 48 and 52**.

LCM(48,52) = 2^{4} × 3^{1} × 13^{1}

LCM(48,52) = 624
