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 13,837,565, 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 | 13,837,565 | |
| -1 | -13,837,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,837,565.
Example:
1 x 13,837,565 = 13,837,565
and
-1 x -13,837,565 = 13,837,565
Notice both answers equal 13,837,565
With that explanation out of the way, let's continue. Next, we take the number 13,837,565 and divide it by 2:
13,837,565 ÷ 2 = 6,918,782.5
If the quotient is a whole number, then 2 and 6,918,782.5 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 | 13,837,565 | |
| -1 | -13,837,565 |
Now, we try dividing 13,837,565 by 3:
13,837,565 ÷ 3 = 4,612,521.6667
If the quotient is a whole number, then 3 and 4,612,521.6667 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 | 13,837,565 | |
| -1 | -13,837,565 |
Let's try dividing by 4:
13,837,565 ÷ 4 = 3,459,391.25
If the quotient is a whole number, then 4 and 3,459,391.25 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 | 13,837,565 | |
| -1 | 13,837,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 6,701 | 33,505 | 46,907 | 234,535 | 395,359 | 1,976,795 | 2,767,513 | 13,837,565 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -6,701 | -33,505 | -46,907 | -234,535 | -395,359 | -1,976,795 | -2,767,513 | -13,837,565 |
