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 13,611,565, 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 | 13,611,565 | |
| -1 | -13,611,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,611,565.
Example:
1 x 13,611,565 = 13,611,565
and
-1 x -13,611,565 = 13,611,565
Notice both answers equal 13,611,565
With that explanation out of the way, let's continue. Next, we take the number 13,611,565 and divide it by 2:
13,611,565 ÷ 2 = 6,805,782.5
If the quotient is a whole number, then 2 and 6,805,782.5 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 | 13,611,565 | |
| -1 | -13,611,565 |
Now, we try dividing 13,611,565 by 3:
13,611,565 ÷ 3 = 4,537,188.3333
If the quotient is a whole number, then 3 and 4,537,188.3333 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 | 13,611,565 | |
| -1 | -13,611,565 |
Let's try dividing by 4:
13,611,565 ÷ 4 = 3,402,891.25
If the quotient is a whole number, then 4 and 3,402,891.25 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 | 13,611,565 | |
| -1 | 13,611,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 263 | 941 | 1,315 | 2,893 | 4,705 | 10,351 | 14,465 | 51,755 | 247,483 | 1,237,415 | 2,722,313 | 13,611,565 |
| -1 | -5 | -11 | -55 | -263 | -941 | -1,315 | -2,893 | -4,705 | -10,351 | -14,465 | -51,755 | -247,483 | -1,237,415 | -2,722,313 | -13,611,565 |
