Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 84, 42, 81, 663 i.e. 501228 smallest integer divisible by all numbers.
Least common multiple (LCM) of 84, 42, 81, 663 is 501228.
LCM(84, 42, 81, 663) = 501228
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 84, 42, 81, 663 |
3 | 42, 21, 81, 663 |
7 | 14, 7, 27, 221 |
2, 1, 27, 221 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 2 x 1 x 27 x 221 = 501228
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 84,42,81,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,42,81,663) = 3
common factors(in case of two or more numbers have common factors) = 126
GCF(84,42,81,663) x common factors =3 x 126 = 378
LCM(84,42,81,663) = ( 84 × 42 × 81 × 663 ) / 378
LCM(84,42,81,663) = 189464184 / 378
LCM(84,42,81,663) = 501228
∴ Least Common Multiple of 84,42,81,663 is 501228
