Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 28, 40, 280 i.e. 280 smallest integer divisible by all numbers.
Least common multiple (LCM) of 28, 40, 280 is 280.
LCM(28, 40, 280) = 280
LCM of 28, 40, 280
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 28, 40, 280 by common division method
- Least Common Multiple of 28, 40, 280 with GCF Formula
Least Common Multiple (LCM) of 28,40,280 is 280
| 2 | 28, 40, 280 |
| 2 | 14, 20, 140 |
| 2 | 7, 10, 70 |
| 5 | 7, 5, 35 |
| 7 | 7, 1, 7 |
| 1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 7 x 1 x 1 x 1 = 280
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 28,40,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,40,280) = 4
common factors(in case of two or more numbers have common factors) = 280
GCF(28,40,280) x common factors =4 x 280 = 1120
LCM(28,40,280) = ( 28 × 40 × 280 ) / 1120
LCM(28,40,280) = 313600 / 1120
LCM(28,40,280) = 280
∴ Least Common Multiple of 28,40,280 is 280
