## LCM of 5 and 10

Least common multiple or lowest common denominator (LCD) can be calculated in three ways;

LCM of:
and ### LCM of 5 and 10 is 10

Least common multiple can be found by multiplying the highest exponent prime factors of 5 and 10. First we will calculate the prime factors of 5 and 10.

Prime Factorization of 5

 5 5 1

Prime factors of 5 are 5. Prime factorization of 5 in exponential form is:

5 = 51

Prime Factorization of 10

 2 10 5 5 1

Prime factors of 10 are 2,5. Prime factorization of 10 in exponential form is:

10 = 21×51

Now multiplying the highest exponent prime factors to calculate the LCM of 5 and 10.

LCM(5,10) = 21×51
LCM(5,10) = 10

### Least Common Multiple of 5 and 10 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 5 and 10, than apply into the LCM equation.

GCF(5,10) = 5
LCM(5,10) = ( 5 × 10) / 5
LCM(5,10) = 50 / 5
LCM(5,10) = 10
