LCM of 686, 819
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 686, 819 by common division method
- Least Common Multiple of 686, 819 with GCF Formula
Least Common Multiple (LCM) of 686,819 is 80262
| 7 | 686, 819 |
| 98, 117 |
∴ So the LCM of the given numbers is 7 x 98 x 117 = 80262
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 686,819 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(686,819) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(686,819) x common factors =7 x 1 = 7
LCM(686,819) = ( 686 × 819 ) / 7
LCM(686,819) = 561834 / 7
LCM(686,819) = 80262
∴ Least Common Multiple of 686,819 is 80262
