LCM(123, 978) = 40098
LCM of 123, 978
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 123, 978 by common division method
- Least Common Multiple of 123, 978 with GCF Formula
Least Common Multiple (LCM) of 123,978 is 40098
| 3 | 123, 978 |
| 41, 326 |
∴ So the LCM of the given numbers is 3 x 41 x 326 = 40098
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 123,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(123,978) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(123,978) x common factors =3 x 1 = 3
LCM(123,978) = ( 123 × 978 ) / 3
LCM(123,978) = 120294 / 3
LCM(123,978) = 40098
∴ Least Common Multiple of 123,978 is 40098
