Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 2, 81, 648 i.e. 648 smallest integer divisible by all numbers.
Least common multiple (LCM) of 2, 81, 648 is 648.
LCM(2, 81, 648) = 648
LCM of 2, 81, 648
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 2, 81, 648 by common division method
- Least Common Multiple of 2, 81, 648 with GCF Formula
Least Common Multiple (LCM) of 2,81,648 is 648
| 2 | 2, 81, 648 |
| 3 | 1, 81, 324 |
| 3 | 1, 27, 108 |
| 3 | 1, 9, 36 |
| 3 | 1, 3, 12 |
| 1, 1, 4 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 1 x 1 x 4 = 648
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 2,81,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2,81,648) = 1
common factors(in case of two or more numbers have common factors) = 162
GCF(2,81,648) x common factors =1 x 162 = 162
LCM(2,81,648) = ( 2 × 81 × 648 ) / 162
LCM(2,81,648) = 104976 / 162
LCM(2,81,648) = 648
∴ Least Common Multiple of 2,81,648 is 648
