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 113,159,579, 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 | 113,159,579 | |
| -1 | -113,159,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,159,579.
Example:
1 x 113,159,579 = 113,159,579
and
-1 x -113,159,579 = 113,159,579
Notice both answers equal 113,159,579
With that explanation out of the way, let's continue. Next, we take the number 113,159,579 and divide it by 2:
113,159,579 ÷ 2 = 56,579,789.5
If the quotient is a whole number, then 2 and 56,579,789.5 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 | 113,159,579 | |
| -1 | -113,159,579 |
Now, we try dividing 113,159,579 by 3:
113,159,579 ÷ 3 = 37,719,859.6667
If the quotient is a whole number, then 3 and 37,719,859.6667 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 | 113,159,579 | |
| -1 | -113,159,579 |
Let's try dividing by 4:
113,159,579 ÷ 4 = 28,289,894.75
If the quotient is a whole number, then 4 and 28,289,894.75 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 | 113,159,579 | |
| -1 | 113,159,579 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 37 | 403 | 481 | 1,147 | 7,589 | 14,911 | 98,657 | 235,259 | 280,793 | 3,058,367 | 3,650,309 | 8,704,583 | 113,159,579 |
| -1 | -13 | -31 | -37 | -403 | -481 | -1,147 | -7,589 | -14,911 | -98,657 | -235,259 | -280,793 | -3,058,367 | -3,650,309 | -8,704,583 | -113,159,579 |
