Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 868, 280, 395 i.e. 685720 smallest integer divisible by all numbers.
Least common multiple (LCM) of 868, 280, 395 is 685720.
LCM(868, 280, 395) = 685720
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 868, 280, 395 |
2 | 434, 140, 395 |
5 | 217, 70, 395 |
7 | 217, 14, 79 |
31, 2, 79 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 31 x 2 x 79 = 685720
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 868,280,395 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(868,280,395) = 1
common factors(in case of two or more numbers have common factors) = 140
GCF(868,280,395) x common factors =1 x 140 = 140
LCM(868,280,395) = ( 868 × 280 × 395 ) / 140
LCM(868,280,395) = 96000800 / 140
LCM(868,280,395) = 685720
∴ Least Common Multiple of 868,280,395 is 685720
