Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 81, 21, 703 i.e. 398601 smallest integer divisible by all numbers.
Least common multiple (LCM) of 81, 21, 703 is 398601.
LCM(81, 21, 703) = 398601
LCM of 81, 21, 703
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 81, 21, 703 by common division method
- Least Common Multiple of 81, 21, 703 with GCF Formula
Least Common Multiple (LCM) of 81,21,703 is 398601
| 3 | 81, 21, 703 |
| 27, 7, 703 |
∴ So the LCM of the given numbers is 3 x 27 x 7 x 703 = 398601
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 81,21,703 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,21,703) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(81,21,703) x common factors =1 x 3 = 3
LCM(81,21,703) = ( 81 × 21 × 703 ) / 3
LCM(81,21,703) = 1195803 / 3
LCM(81,21,703) = 398601
∴ Least Common Multiple of 81,21,703 is 398601
