Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 69, 810, 345 i.e. 18630 smallest integer divisible by all numbers.
Least common multiple (LCM) of 69, 810, 345 is 18630.
LCM(69, 810, 345) = 18630
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 69, 810, 345 |
5 | 23, 270, 115 |
23 | 23, 54, 23 |
1, 54, 1 |
∴ So the LCM of the given numbers is 3 x 5 x 23 x 1 x 54 x 1 = 18630
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 69,810,345 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,810,345) = 3
common factors(in case of two or more numbers have common factors) = 345
GCF(69,810,345) x common factors =3 x 345 = 1035
LCM(69,810,345) = ( 69 × 810 × 345 ) / 1035
LCM(69,810,345) = 19282050 / 1035
LCM(69,810,345) = 18630
∴ Least Common Multiple of 69,810,345 is 18630
