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 13,797,665, 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 | 13,797,665 | |
| -1 | -13,797,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,797,665.
Example:
1 x 13,797,665 = 13,797,665
and
-1 x -13,797,665 = 13,797,665
Notice both answers equal 13,797,665
With that explanation out of the way, let's continue. Next, we take the number 13,797,665 and divide it by 2:
13,797,665 ÷ 2 = 6,898,832.5
If the quotient is a whole number, then 2 and 6,898,832.5 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 | 13,797,665 | |
| -1 | -13,797,665 |
Now, we try dividing 13,797,665 by 3:
13,797,665 ÷ 3 = 4,599,221.6667
If the quotient is a whole number, then 3 and 4,599,221.6667 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 | 13,797,665 | |
| -1 | -13,797,665 |
Let's try dividing by 4:
13,797,665 ÷ 4 = 3,449,416.25
If the quotient is a whole number, then 4 and 3,449,416.25 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 | 13,797,665 | |
| -1 | 13,797,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 199 | 245 | 283 | 995 | 1,393 | 1,415 | 1,981 | 6,965 | 9,751 | 9,905 | 13,867 | 48,755 | 56,317 | 69,335 | 281,585 | 394,219 | 1,971,095 | 2,759,533 | 13,797,665 |
| -1 | -5 | -7 | -35 | -49 | -199 | -245 | -283 | -995 | -1,393 | -1,415 | -1,981 | -6,965 | -9,751 | -9,905 | -13,867 | -48,755 | -56,317 | -69,335 | -281,585 | -394,219 | -1,971,095 | -2,759,533 | -13,797,665 |
