Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 20, 10, 40 i.e. 40 smallest integer divisible by all numbers.
Least common multiple (LCM) of 20, 10, 40 is 40.
LCM(20, 10, 40) = 40
LCM of 20, 10, 40
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 20, 10, 40 by common division method
- Least Common Multiple of 20, 10, 40 with GCF Formula
Least Common Multiple (LCM) of 20,10,40 is 40
| 2 | 20, 10, 40 |
| 2 | 10, 5, 20 |
| 5 | 5, 5, 10 |
| 1, 1, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 1 x 2 = 40
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 20,10,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,10,40) = 10
common factors(in case of two or more numbers have common factors) = 20
GCF(20,10,40) x common factors =10 x 20 = 200
LCM(20,10,40) = ( 20 × 10 × 40 ) / 200
LCM(20,10,40) = 8000 / 200
LCM(20,10,40) = 40
∴ Least Common Multiple of 20,10,40 is 40
