Least common multiple (LCM) of 90, 1998 is 9990.
LCM(90, 1998) = 9990
LCM of 90, 1998
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 90, 1998 by common division method
- Least Common Multiple of 90, 1998 with GCF Formula
Least Common Multiple (LCM) of 90,1998 is 9990
| 2 | 90, 1998 |
| 3 | 45, 999 |
| 3 | 15, 333 |
| 5, 111 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 111 = 9990
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 90,1998 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,1998) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(90,1998) x common factors =18 x 1 = 18
LCM(90,1998) = ( 90 × 1998 ) / 18
LCM(90,1998) = 179820 / 18
LCM(90,1998) = 9990
∴ Least Common Multiple of 90,1998 is 9990
