Least common multiple (LCM) of 7, 81, 378 is 1134.
LCM(7, 81, 378) = 1134
LCM of 7, 81, 378
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 7, 81, 378 by common division method
- Least Common Multiple of 7, 81, 378 with GCF Formula
Least Common Multiple (LCM) of 7,81,378 is 1134
| 3 | 7, 81, 378 |
| 3 | 7, 27, 126 |
| 3 | 7, 9, 42 |
| 7 | 7, 3, 14 |
| 1, 3, 2 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 7 x 1 x 3 x 2 = 1134
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 7,81,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7,81,378) = 1
common factors(in case of two or more numbers have common factors) = 189
GCF(7,81,378) x common factors =1 x 189 = 189
LCM(7,81,378) = ( 7 × 81 × 378 ) / 189
LCM(7,81,378) = 214326 / 189
LCM(7,81,378) = 1134
∴ Least Common Multiple of 7,81,378 is 1134
