Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 21, 68, 77, 418 i.e. 298452 smallest integer divisible by all numbers.
Least common multiple (LCM) of 21, 68, 77, 418 is 298452.
LCM(21, 68, 77, 418) = 298452
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 21, 68, 77, 418 |
7 | 21, 34, 77, 209 |
11 | 3, 34, 11, 209 |
3, 34, 1, 19 |
∴ So the LCM of the given numbers is 2 x 7 x 11 x 3 x 34 x 1 x 19 = 298452
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 21,68,77,418 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,68,77,418) = 1
common factors(in case of two or more numbers have common factors) = 154
GCF(21,68,77,418) x common factors =1 x 154 = 154
LCM(21,68,77,418) = ( 21 × 68 × 77 × 418 ) / 154
LCM(21,68,77,418) = 45961608 / 154
LCM(21,68,77,418) = 298452
∴ Least Common Multiple of 21,68,77,418 is 298452
