Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 800, 640 i.e. 3200 smallest integer divisible by all numbers.
Least common multiple (LCM) of 800, 640 is 3200.
LCM(800, 640) = 3200
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 800, 640 |
2 | 400, 320 |
2 | 200, 160 |
2 | 100, 80 |
2 | 50, 40 |
5 | 25, 20 |
5, 4 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 5 x 5 x 4 = 3200
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 800,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(800,640) = 160
common factors(in case of two or more numbers have common factors) = 1
GCF(800,640) x common factors =160 x 1 = 160
LCM(800,640) = ( 800 × 640 ) / 160
LCM(800,640) = 512000 / 160
LCM(800,640) = 3200
∴ Least Common Multiple of 800,640 is 3200
Here are some samples of LCM of two or more Numbers calculations.
