Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 28, 40, 910 i.e. 3640 smallest integer divisible by all numbers.
Least common multiple (LCM) of 28, 40, 910 is 3640.
LCM(28, 40, 910) = 3640
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 28, 40, 910 |
2 | 14, 20, 455 |
5 | 7, 10, 455 |
7 | 7, 2, 91 |
1, 2, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 2 x 13 = 3640
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 28,40,910 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,40,910) = 2
common factors(in case of two or more numbers have common factors) = 140
GCF(28,40,910) x common factors =2 x 140 = 280
LCM(28,40,910) = ( 28 × 40 × 910 ) / 280
LCM(28,40,910) = 1019200 / 280
LCM(28,40,910) = 3640
∴ Least Common Multiple of 28,40,910 is 3640
