Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 65, 60, 390 i.e. 780 smallest integer divisible by all numbers.
Least common multiple (LCM) of 65, 60, 390 is 780.
LCM(65, 60, 390) = 780
LCM of 65, 60, 390
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 65, 60, 390 by common division method
- Least Common Multiple of 65, 60, 390 with GCF Formula
Least Common Multiple (LCM) of 65,60,390 is 780
| 2 | 65, 60, 390 |
| 3 | 65, 30, 195 |
| 5 | 65, 10, 65 |
| 13 | 13, 2, 13 |
| 1, 2, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 13 x 1 x 2 x 1 = 780
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 65,60,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,60,390) = 5
common factors(in case of two or more numbers have common factors) = 390
GCF(65,60,390) x common factors =5 x 390 = 1950
LCM(65,60,390) = ( 65 × 60 × 390 ) / 1950
LCM(65,60,390) = 1521000 / 1950
LCM(65,60,390) = 780
∴ Least Common Multiple of 65,60,390 is 780
