Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 65, 15, 78 i.e. 390 smallest integer divisible by all numbers.
Least common multiple (LCM) of 65, 15, 78 is 390.
LCM(65, 15, 78) = 390
LCM of 65, 15, 78
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 65, 15, 78 by common division method
- Least Common Multiple of 65, 15, 78 with GCF Formula
Least Common Multiple (LCM) of 65,15,78 is 390
| 3 | 65, 15, 78 |
| 5 | 65, 5, 26 |
| 13 | 13, 1, 26 |
| 1, 1, 2 |
∴ So the LCM of the given numbers is 3 x 5 x 13 x 1 x 1 x 2 = 390
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 65,15,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,15,78) = 1
common factors(in case of two or more numbers have common factors) = 195
GCF(65,15,78) x common factors =1 x 195 = 195
LCM(65,15,78) = ( 65 × 15 × 78 ) / 195
LCM(65,15,78) = 76050 / 195
LCM(65,15,78) = 390
∴ Least Common Multiple of 65,15,78 is 390
