Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 90, 18, 126 i.e. 630 smallest integer divisible by all numbers.
Least common multiple (LCM) of 90, 18, 126 is 630.
LCM(90, 18, 126) = 630
LCM of 90, 18, 126
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 90, 18, 126 by common division method
- Least Common Multiple of 90, 18, 126 with GCF Formula
Least Common Multiple (LCM) of 90,18,126 is 630
| 2 | 90, 18, 126 |
| 3 | 45, 9, 63 |
| 3 | 15, 3, 21 |
| 5, 1, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 1 x 7 = 630
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 90,18,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,18,126) = 18
common factors(in case of two or more numbers have common factors) = 18
GCF(90,18,126) x common factors =18 x 18 = 324
LCM(90,18,126) = ( 90 × 18 × 126 ) / 324
LCM(90,18,126) = 204120 / 324
LCM(90,18,126) = 630
∴ Least Common Multiple of 90,18,126 is 630
