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 113,035,013, 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 | 113,035,013 | |
| -1 | -113,035,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,035,013.
Example:
1 x 113,035,013 = 113,035,013
and
-1 x -113,035,013 = 113,035,013
Notice both answers equal 113,035,013
With that explanation out of the way, let's continue. Next, we take the number 113,035,013 and divide it by 2:
113,035,013 ÷ 2 = 56,517,506.5
If the quotient is a whole number, then 2 and 56,517,506.5 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 | 113,035,013 | |
| -1 | -113,035,013 |
Now, we try dividing 113,035,013 by 3:
113,035,013 ÷ 3 = 37,678,337.6667
If the quotient is a whole number, then 3 and 37,678,337.6667 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 | 113,035,013 | |
| -1 | -113,035,013 |
Let's try dividing by 4:
113,035,013 ÷ 4 = 28,258,753.25
If the quotient is a whole number, then 4 and 28,258,753.25 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 | 113,035,013 | |
| -1 | 113,035,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 61 | 91 | 427 | 637 | 793 | 2,909 | 2,989 | 5,551 | 20,363 | 37,817 | 38,857 | 142,541 | 177,449 | 264,719 | 1,242,143 | 1,853,033 | 2,306,837 | 8,695,001 | 16,147,859 | 113,035,013 |
| -1 | -7 | -13 | -49 | -61 | -91 | -427 | -637 | -793 | -2,909 | -2,989 | -5,551 | -20,363 | -37,817 | -38,857 | -142,541 | -177,449 | -264,719 | -1,242,143 | -1,853,033 | -2,306,837 | -8,695,001 | -16,147,859 | -113,035,013 |
