Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 128, 168, 820, 630 i.e. 1653120 smallest integer divisible by all numbers.
Least common multiple (LCM) of 128, 168, 820, 630 is 1653120.
LCM(128, 168, 820, 630) = 1653120
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 128, 168, 820, 630 |
2 | 64, 84, 410, 315 |
2 | 32, 42, 205, 315 |
3 | 16, 21, 205, 315 |
5 | 16, 7, 205, 105 |
7 | 16, 7, 41, 21 |
16, 1, 41, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 7 x 16 x 1 x 41 x 3 = 1653120
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 128,168,820,630 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,168,820,630) = 2
common factors(in case of two or more numbers have common factors) = 3360
GCF(128,168,820,630) x common factors =2 x 3360 = 6720
LCM(128,168,820,630) = ( 128 × 168 × 820 × 630 ) / 6720
LCM(128,168,820,630) = 11108966400 / 6720
LCM(128,168,820,630) = 1653120
∴ Least Common Multiple of 128,168,820,630 is 1653120
