Least common multiple (LCM) of 17, 21, 357 is 357.
LCM(17, 21, 357) = 357
LCM of 17, 21, 357
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 17, 21, 357 by common division method
- Least Common Multiple of 17, 21, 357 with GCF Formula
Least Common Multiple (LCM) of 17,21,357 is 357
| 3 | 17, 21, 357 |
| 7 | 17, 7, 119 |
| 17 | 17, 1, 17 |
| 1, 1, 1 |
∴ So the LCM of the given numbers is 3 x 7 x 17 x 1 x 1 x 1 = 357
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 17,21,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,21,357) = 1
common factors(in case of two or more numbers have common factors) = 357
GCF(17,21,357) x common factors =1 x 357 = 357
LCM(17,21,357) = ( 17 × 21 × 357 ) / 357
LCM(17,21,357) = 127449 / 357
LCM(17,21,357) = 357
∴ Least Common Multiple of 17,21,357 is 357
