Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 18, 84, 30, 822 i.e. 172620 smallest integer divisible by all numbers.
Least common multiple (LCM) of 18, 84, 30, 822 is 172620.
LCM(18, 84, 30, 822) = 172620
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 18, 84, 30, 822 |
3 | 9, 42, 15, 411 |
3, 14, 5, 137 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 14 x 5 x 137 = 172620
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 18,84,30,822 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,84,30,822) = 6
common factors(in case of two or more numbers have common factors) = 36
GCF(18,84,30,822) x common factors =6 x 36 = 216
LCM(18,84,30,822) = ( 18 × 84 × 30 × 822 ) / 216
LCM(18,84,30,822) = 37285920 / 216
LCM(18,84,30,822) = 172620
∴ Least Common Multiple of 18,84,30,822 is 172620
