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 15,567,563, 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 | 15,567,563 | |
| -1 | -15,567,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,567,563.
Example:
1 x 15,567,563 = 15,567,563
and
-1 x -15,567,563 = 15,567,563
Notice both answers equal 15,567,563
With that explanation out of the way, let's continue. Next, we take the number 15,567,563 and divide it by 2:
15,567,563 ÷ 2 = 7,783,781.5
If the quotient is a whole number, then 2 and 7,783,781.5 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 | 15,567,563 | |
| -1 | -15,567,563 |
Now, we try dividing 15,567,563 by 3:
15,567,563 ÷ 3 = 5,189,187.6667
If the quotient is a whole number, then 3 and 5,189,187.6667 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 | 15,567,563 | |
| -1 | -15,567,563 |
Let's try dividing by 4:
15,567,563 ÷ 4 = 3,891,890.75
If the quotient is a whole number, then 4 and 3,891,890.75 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 | 15,567,563 | |
| -1 | 15,567,563 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 59 | 83 | 187 | 289 | 649 | 913 | 1,003 | 1,411 | 3,179 | 4,897 | 11,033 | 15,521 | 17,051 | 23,987 | 53,867 | 83,249 | 187,561 | 263,857 | 915,739 | 1,415,233 | 15,567,563 |
| -1 | -11 | -17 | -59 | -83 | -187 | -289 | -649 | -913 | -1,003 | -1,411 | -3,179 | -4,897 | -11,033 | -15,521 | -17,051 | -23,987 | -53,867 | -83,249 | -187,561 | -263,857 | -915,739 | -1,415,233 | -15,567,563 |
