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 13,937,417, 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 | 13,937,417 | |
| -1 | -13,937,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,937,417.
Example:
1 x 13,937,417 = 13,937,417
and
-1 x -13,937,417 = 13,937,417
Notice both answers equal 13,937,417
With that explanation out of the way, let's continue. Next, we take the number 13,937,417 and divide it by 2:
13,937,417 ÷ 2 = 6,968,708.5
If the quotient is a whole number, then 2 and 6,968,708.5 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 | 13,937,417 | |
| -1 | -13,937,417 |
Now, we try dividing 13,937,417 by 3:
13,937,417 ÷ 3 = 4,645,805.6667
If the quotient is a whole number, then 3 and 4,645,805.6667 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 | 13,937,417 | |
| -1 | -13,937,417 |
Let's try dividing by 4:
13,937,417 ÷ 4 = 3,484,354.25
If the quotient is a whole number, then 4 and 3,484,354.25 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 | 13,937,417 | |
| -1 | 13,937,417 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 79 | 331 | 533 | 1,027 | 3,239 | 4,303 | 13,571 | 26,149 | 42,107 | 176,423 | 339,937 | 1,072,109 | 13,937,417 |
| -1 | -13 | -41 | -79 | -331 | -533 | -1,027 | -3,239 | -4,303 | -13,571 | -26,149 | -42,107 | -176,423 | -339,937 | -1,072,109 | -13,937,417 |
