Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 81, 22, 861 i.e. 511434 smallest integer divisible by all numbers.
Least common multiple (LCM) of 81, 22, 861 is 511434.
LCM(81, 22, 861) = 511434
LCM of 81, 22, 861
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 81, 22, 861 by common division method
- Least Common Multiple of 81, 22, 861 with GCF Formula
Least Common Multiple (LCM) of 81,22,861 is 511434
| 3 | 81, 22, 861 |
| 27, 22, 287 |
∴ So the LCM of the given numbers is 3 x 27 x 22 x 287 = 511434
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 81,22,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,22,861) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(81,22,861) x common factors =1 x 3 = 3
LCM(81,22,861) = ( 81 × 22 × 861 ) / 3
LCM(81,22,861) = 1534302 / 3
LCM(81,22,861) = 511434
∴ Least Common Multiple of 81,22,861 is 511434
