Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 14,015,071, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 14,015,071 | |
| -1 | -14,015,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,015,071.
Example:
1 x 14,015,071 = 14,015,071
and
-1 x -14,015,071 = 14,015,071
Notice both answers equal 14,015,071
With that explanation out of the way, let's continue. Next, we take the number 14,015,071 and divide it by 2:
14,015,071 ÷ 2 = 7,007,535.5
If the quotient is a whole number, then 2 and 7,007,535.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 14,015,071 | |
| -1 | -14,015,071 |
Now, we try dividing 14,015,071 by 3:
14,015,071 ÷ 3 = 4,671,690.3333
If the quotient is a whole number, then 3 and 4,671,690.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 14,015,071 | |
| -1 | -14,015,071 |
Let's try dividing by 4:
14,015,071 ÷ 4 = 3,503,767.75
If the quotient is a whole number, then 4 and 3,503,767.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 14,015,071 | |
| -1 | 14,015,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 47 | 287 | 329 | 1,039 | 1,927 | 7,273 | 13,489 | 42,599 | 48,833 | 298,193 | 341,831 | 2,002,153 | 14,015,071 |
| -1 | -7 | -41 | -47 | -287 | -329 | -1,039 | -1,927 | -7,273 | -13,489 | -42,599 | -48,833 | -298,193 | -341,831 | -2,002,153 | -14,015,071 |
