Least common multiple (LCM) of 15, 123 is 615.
LCM(15, 123) = 615
LCM of 15, 123
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 15, 123 by common division method
- Least Common Multiple of 15, 123 with GCF Formula
Least Common Multiple (LCM) of 15,123 is 615
| 3 | 15, 123 |
| 5, 41 |
∴ So the LCM of the given numbers is 3 x 5 x 41 = 615
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 15,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,123) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(15,123) x common factors =3 x 1 = 3
LCM(15,123) = ( 15 × 123 ) / 3
LCM(15,123) = 1845 / 3
LCM(15,123) = 615
∴ Least Common Multiple of 15,123 is 615
