# What is the Least Common Multiple of 59 and 73?

*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 59 and 73 is **4307**.

LCM(59,73) = 4307

## Least Common Multiple of 59 and 73 with GCF Formula

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

We need to calculate greatest common factor 59 and 73, than apply into the LCM equation.

GCF(59,73) = 1

LCM(59,73) = ( 59 × 73) / 1

LCM(59,73) = 4307 / 1

LCM(59,73) = 4307

## Least Common Multiple (LCM) of 59 and 73 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 59 and 73. First we will calculate the **prime factors of 59 and 73**.

### Prime Factorization of 59

Prime factors of 59 are 59. Prime factorization of **59** in exponential form is:

59 = 59^{1}

### Prime Factorization of 73

Prime factors of 73 are 73. Prime factorization of **73** in exponential form is:

73 = 73^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 59 and 73**.

LCM(59,73) = 59^{1} × 73^{1}

LCM(59,73) = 4307
