LCM(831, 438) = 121326
LCM of 831, 438
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 831, 438 by common division method
- Least Common Multiple of 831, 438 with GCF Formula
Least Common Multiple (LCM) of 831,438 is 121326
| 3 | 831, 438 |
| 277, 146 |
∴ So the LCM of the given numbers is 3 x 277 x 146 = 121326
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 831,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(831,438) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(831,438) x common factors =3 x 1 = 3
LCM(831,438) = ( 831 × 438 ) / 3
LCM(831,438) = 363978 / 3
LCM(831,438) = 121326
∴ Least Common Multiple of 831,438 is 121326
