Least common multiple (LCM) of 18, 7128 is 7128.
LCM(18, 7128) = 7128
LCM of 18, 7128
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 18, 7128 by common division method
- Least Common Multiple of 18, 7128 with GCF Formula
Least Common Multiple (LCM) of 18,7128 is 7128
| 2 | 18, 7128 |
| 3 | 9, 3564 |
| 3 | 3, 1188 |
| 1, 396 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 396 = 7128
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 18,7128 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,7128) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(18,7128) x common factors =18 x 1 = 18
LCM(18,7128) = ( 18 × 7128 ) / 18
LCM(18,7128) = 128304 / 18
LCM(18,7128) = 7128
∴ Least Common Multiple of 18,7128 is 7128
