# What is the Least Common Multiple of 120 and 131?

*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 120 and 131 is **15720**.

LCM(120,131) = 15720

## Least Common Multiple of 120 and 131 with GCF Formula

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

We need to calculate greatest common factor 120 and 131, than apply into the LCM equation.

GCF(120,131) = 1

LCM(120,131) = ( 120 × 131) / 1

LCM(120,131) = 15720 / 1

LCM(120,131) = 15720

## Least Common Multiple (LCM) of 120 and 131 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 120 and 131. First we will calculate the **prime factors of 120 and 131**.

### Prime Factorization of 120

Prime factors of 120 are 2, 3, 5. Prime factorization of **120** in exponential form is:

120 = 2^{3} × 3^{1} × 5^{1}

### Prime Factorization of 131

Prime factors of 131 are 131. Prime factorization of **131** in exponential form is:

131 = 131^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 120 and 131**.

LCM(120,131) = 2^{3} × 3^{1} × 5^{1} × 131^{1}

LCM(120,131) = 15720
