Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 63, 81, 69, 490 i.e. 912870 smallest integer divisible by all numbers.
Least common multiple (LCM) of 63, 81, 69, 490 is 912870.
LCM(63, 81, 69, 490) = 912870
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 63, 81, 69, 490 |
3 | 21, 27, 23, 490 |
7 | 7, 9, 23, 490 |
1, 9, 23, 70 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 1 x 9 x 23 x 70 = 912870
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 63,81,69,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,81,69,490) = 1
common factors(in case of two or more numbers have common factors) = 189
GCF(63,81,69,490) x common factors =1 x 189 = 189
LCM(63,81,69,490) = ( 63 × 81 × 69 × 490 ) / 189
LCM(63,81,69,490) = 172532430 / 189
LCM(63,81,69,490) = 912870
∴ Least Common Multiple of 63,81,69,490 is 912870
