Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 820, 375, 680 i.e. 2091000 smallest integer divisible by all numbers.
Least common multiple (LCM) of 820, 375, 680 is 2091000.
LCM(820, 375, 680) = 2091000
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 820, 375, 680 |
2 | 410, 375, 340 |
5 | 205, 375, 170 |
41, 75, 34 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 41 x 75 x 34 = 2091000
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 820,375,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,375,680) = 5
common factors(in case of two or more numbers have common factors) = 20
GCF(820,375,680) x common factors =5 x 20 = 100
LCM(820,375,680) = ( 820 × 375 × 680 ) / 100
LCM(820,375,680) = 209100000 / 100
LCM(820,375,680) = 2091000
∴ Least Common Multiple of 820,375,680 is 2091000
