Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 86, 91, 63, 72 i.e. 281736 smallest integer divisible by all numbers.
Least common multiple (LCM) of 86, 91, 63, 72 is 281736.
LCM(86, 91, 63, 72) = 281736
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 86, 91, 63, 72 |
3 | 43, 91, 63, 36 |
3 | 43, 91, 21, 12 |
7 | 43, 91, 7, 4 |
43, 13, 1, 4 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 43 x 13 x 1 x 4 = 281736
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 86,91,63,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,91,63,72) = 1
common factors(in case of two or more numbers have common factors) = 126
GCF(86,91,63,72) x common factors =1 x 126 = 126
LCM(86,91,63,72) = ( 86 × 91 × 63 × 72 ) / 126
LCM(86,91,63,72) = 35498736 / 126
LCM(86,91,63,72) = 281736
∴ Least Common Multiple of 86,91,63,72 is 281736
