Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 861, 639, 308, 222, 426 i.e. 298563804 smallest integer divisible by all numbers.
Least common multiple (LCM) of 861, 639, 308, 222, 426 is 298563804.
LCM(861, 639, 308, 222, 426) = 298563804
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 861, 639, 308, 222, 426 |
3 | 861, 639, 154, 111, 213 |
7 | 287, 71, 154, 37, 213 |
71 | 41, 71, 22, 37, 213 |
41, 1, 22, 37, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 71 x 41 x 1 x 22 x 37 x 3 = 298563804
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 861,639,308,222,426 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(861,639,308,222,426) = 1
common factors(in case of two or more numbers have common factors) = 53676
GCF(861,639,308,222,426) x common factors =1 x 53676 = 53676
LCM(861,639,308,222,426) = ( 861 × 639 × 308 × 222 × 426 ) / 53676
LCM(861,639,308,222,426) = 16025710743504 / 53676
LCM(861,639,308,222,426) = 298563804
∴ Least Common Multiple of 861,639,308,222,426 is 298563804
