Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 34, 84, 84, 72 i.e. 8568 smallest integer divisible by all numbers.
Least common multiple (LCM) of 34, 84, 84, 72 is 8568.
LCM(34, 84, 84, 72) = 8568
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 34, 84, 84, 72 |
2 | 17, 42, 42, 36 |
3 | 17, 21, 21, 18 |
7 | 17, 7, 7, 6 |
17, 1, 1, 6 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 17 x 1 x 1 x 6 = 8568
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 34,84,84,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,84,84,72) = 2
common factors(in case of two or more numbers have common factors) = 1008
GCF(34,84,84,72) x common factors =2 x 1008 = 2016
LCM(34,84,84,72) = ( 34 × 84 × 84 × 72 ) / 2016
LCM(34,84,84,72) = 17273088 / 2016
LCM(34,84,84,72) = 8568
∴ Least Common Multiple of 34,84,84,72 is 8568
