Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 4, 80, 320 i.e. 320 smallest integer divisible by all numbers.
Least common multiple (LCM) of 4, 80, 320 is 320.
LCM(4, 80, 320) = 320
LCM of 4, 80, 320
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 4, 80, 320 by common division method
- Least Common Multiple of 4, 80, 320 with GCF Formula
Least Common Multiple (LCM) of 4,80,320 is 320
| 2 | 4, 80, 320 |
| 2 | 2, 40, 160 |
| 2 | 1, 20, 80 |
| 2 | 1, 10, 40 |
| 5 | 1, 5, 20 |
| 1, 1, 4 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 1 x 4 = 320
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 4,80,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(4,80,320) = 4
common factors(in case of two or more numbers have common factors) = 80
GCF(4,80,320) x common factors =4 x 80 = 320
LCM(4,80,320) = ( 4 × 80 × 320 ) / 320
LCM(4,80,320) = 102400 / 320
LCM(4,80,320) = 320
∴ Least Common Multiple of 4,80,320 is 320
