Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 870, 245, 638 i.e. 468930 smallest integer divisible by all numbers.
Least common multiple (LCM) of 870, 245, 638 is 468930.
LCM(870, 245, 638) = 468930
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 870, 245, 638 |
5 | 435, 245, 319 |
29 | 87, 49, 319 |
3, 49, 11 |
∴ So the LCM of the given numbers is 2 x 5 x 29 x 3 x 49 x 11 = 468930
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 870,245,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(870,245,638) = 1
common factors(in case of two or more numbers have common factors) = 290
GCF(870,245,638) x common factors =1 x 290 = 290
LCM(870,245,638) = ( 870 × 245 × 638 ) / 290
LCM(870,245,638) = 135989700 / 290
LCM(870,245,638) = 468930
∴ Least Common Multiple of 870,245,638 is 468930
