Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 108, 18, 390 i.e. 7020 smallest integer divisible by all numbers.
Least common multiple (LCM) of 108, 18, 390 is 7020.
LCM(108, 18, 390) = 7020
LCM of 108, 18, 390
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 108, 18, 390 by common division method
- Least Common Multiple of 108, 18, 390 with GCF Formula
Least Common Multiple (LCM) of 108,18,390 is 7020
| 2 | 108, 18, 390 |
| 3 | 54, 9, 195 |
| 3 | 18, 3, 65 |
| 6, 1, 65 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 6 x 1 x 65 = 7020
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 108,18,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(108,18,390) = 6
common factors(in case of two or more numbers have common factors) = 18
GCF(108,18,390) x common factors =6 x 18 = 108
LCM(108,18,390) = ( 108 × 18 × 390 ) / 108
LCM(108,18,390) = 758160 / 108
LCM(108,18,390) = 7020
∴ Least Common Multiple of 108,18,390 is 7020
