Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 36, 81, 621 i.e. 7452 smallest integer divisible by all numbers.
Least common multiple (LCM) of 36, 81, 621 is 7452.
LCM(36, 81, 621) = 7452
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 36, 81, 621 |
3 | 12, 27, 207 |
3 | 4, 9, 69 |
4, 3, 23 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 4 x 3 x 23 = 7452
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 36,81,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,81,621) = 9
common factors(in case of two or more numbers have common factors) = 27
GCF(36,81,621) x common factors =9 x 27 = 243
LCM(36,81,621) = ( 36 × 81 × 621 ) / 243
LCM(36,81,621) = 1810836 / 243
LCM(36,81,621) = 7452
∴ Least Common Multiple of 36,81,621 is 7452
