Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 243, 324, 42 i.e. 6804 smallest integer divisible by all numbers.
Least common multiple (LCM) of 243, 324, 42 is 6804.
LCM(243, 324, 42) = 6804
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 243, 324, 42 |
3 | 243, 162, 21 |
3 | 81, 54, 7 |
3 | 27, 18, 7 |
3 | 9, 6, 7 |
3, 2, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 3 x 2 x 7 = 6804
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 243,324,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,324,42) = 3
common factors(in case of two or more numbers have common factors) = 162
GCF(243,324,42) x common factors =3 x 162 = 486
LCM(243,324,42) = ( 243 × 324 × 42 ) / 486
LCM(243,324,42) = 3306744 / 486
LCM(243,324,42) = 6804
∴ Least Common Multiple of 243,324,42 is 6804
