- Least Common Multiple of 945, 3969 with GCF Formula
Least Common Multiple (LCM) of 945,3969 is 19845
| 3 | 945, 3969 |
| 3 | 315, 1323 |
| 3 | 105, 441 |
| 7 | 35, 147 |
| 5, 21 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 7 x 5 x 21 = 19845
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 945,3969 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,3969) = 189
common factors(in case of two or more numbers have common factors) = 1
GCF(945,3969) x common factors =189 x 1 = 189
LCM(945,3969) = ( 945 × 3969 ) / 189
LCM(945,3969) = 3750705 / 189
LCM(945,3969) = 19845
∴ Least Common Multiple of 945,3969 is 19845
