Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 81, 81, 642 i.e. 17334 smallest integer divisible by all numbers.
Least common multiple (LCM) of 81, 81, 642 is 17334.
LCM(81, 81, 642) = 17334
LCM of 81, 81, 642
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 81, 81, 642 by common division method
- Least Common Multiple of 81, 81, 642 with GCF Formula
Least Common Multiple (LCM) of 81,81,642 is 17334
| 3 | 81, 81, 642 |
| 3 | 27, 27, 214 |
| 3 | 9, 9, 214 |
| 3 | 3, 3, 214 |
| 1, 1, 214 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 1 x 1 x 214 = 17334
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 81,81,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,81,642) = 3
common factors(in case of two or more numbers have common factors) = 81
GCF(81,81,642) x common factors =3 x 81 = 243
LCM(81,81,642) = ( 81 × 81 × 642 ) / 243
LCM(81,81,642) = 4212162 / 243
LCM(81,81,642) = 17334
∴ Least Common Multiple of 81,81,642 is 17334
