Least common multiple (LCM) of 21, 65, 783 is 356265.
LCM(21, 65, 783) = 356265
LCM of 21, 65, 783
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 21, 65, 783 by common division method
- Least Common Multiple of 21, 65, 783 with GCF Formula
Least Common Multiple (LCM) of 21,65,783 is 356265
| 3 | 21, 65, 783 |
| 7, 65, 261 |
∴ So the LCM of the given numbers is 3 x 7 x 65 x 261 = 356265
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 21,65,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,65,783) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(21,65,783) x common factors =1 x 3 = 3
LCM(21,65,783) = ( 21 × 65 × 783 ) / 3
LCM(21,65,783) = 1068795 / 3
LCM(21,65,783) = 356265
∴ Least Common Multiple of 21,65,783 is 356265
