Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 57, 80, 60, 861 i.e. 1308720 smallest integer divisible by all numbers.
Least common multiple (LCM) of 57, 80, 60, 861 is 1308720.
LCM(57, 80, 60, 861) = 1308720
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 57, 80, 60, 861 |
2 | 57, 40, 30, 861 |
3 | 57, 20, 15, 861 |
5 | 19, 20, 5, 287 |
19, 4, 1, 287 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 19 x 4 x 1 x 287 = 1308720
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 57,80,60,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,80,60,861) = 1
common factors(in case of two or more numbers have common factors) = 180
GCF(57,80,60,861) x common factors =1 x 180 = 180
LCM(57,80,60,861) = ( 57 × 80 × 60 × 861 ) / 180
LCM(57,80,60,861) = 235569600 / 180
LCM(57,80,60,861) = 1308720
∴ Least Common Multiple of 57,80,60,861 is 1308720
