LCM(21, 4081) = 12243
LCM of 21, 4081
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 21, 4081 by common division method
- Least Common Multiple of 21, 4081 with GCF Formula
Least Common Multiple (LCM) of 21,4081 is 12243
| 7 | 21, 4081 |
| 3, 583 |
∴ So the LCM of the given numbers is 7 x 3 x 583 = 12243
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 21,4081 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,4081) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(21,4081) x common factors =7 x 1 = 7
LCM(21,4081) = ( 21 × 4081 ) / 7
LCM(21,4081) = 85701 / 7
LCM(21,4081) = 12243
∴ Least Common Multiple of 21,4081 is 12243
