Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 22, 21, 231 i.e. 462 smallest integer divisible by all numbers.
Least common multiple (LCM) of 22, 21, 231 is 462.
LCM(22, 21, 231) = 462
LCM of 22, 21, 231
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 22, 21, 231 by common division method
- Least Common Multiple of 22, 21, 231 with GCF Formula
Least Common Multiple (LCM) of 22,21,231 is 462
| 3 | 22, 21, 231 |
| 7 | 22, 7, 77 |
| 11 | 22, 1, 11 |
| 2, 1, 1 |
∴ So the LCM of the given numbers is 3 x 7 x 11 x 2 x 1 x 1 = 462
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 22,21,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,21,231) = 1
common factors(in case of two or more numbers have common factors) = 231
GCF(22,21,231) x common factors =1 x 231 = 231
LCM(22,21,231) = ( 22 × 21 × 231 ) / 231
LCM(22,21,231) = 106722 / 231
LCM(22,21,231) = 462
∴ Least Common Multiple of 22,21,231 is 462
