Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 81, 27, 105, 813 i.e. 768285 smallest integer divisible by all numbers.
Least common multiple (LCM) of 81, 27, 105, 813 is 768285.
LCM(81, 27, 105, 813) = 768285
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 81, 27, 105, 813 |
3 | 27, 9, 35, 271 |
3 | 3, 9, 35, 271 |
1, 3, 35, 271 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 1 x 3 x 35 x 271 = 768285
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 81,27,105,813 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,27,105,813) = 3
common factors(in case of two or more numbers have common factors) = 81
GCF(81,27,105,813) x common factors =3 x 81 = 243
LCM(81,27,105,813) = ( 81 × 27 × 105 × 813 ) / 243
LCM(81,27,105,813) = 186693255 / 243
LCM(81,27,105,813) = 768285
∴ Least Common Multiple of 81,27,105,813 is 768285
