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 113,020,145, 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 | 113,020,145 | |
| -1 | -113,020,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,020,145.
Example:
1 x 113,020,145 = 113,020,145
and
-1 x -113,020,145 = 113,020,145
Notice both answers equal 113,020,145
With that explanation out of the way, let's continue. Next, we take the number 113,020,145 and divide it by 2:
113,020,145 ÷ 2 = 56,510,072.5
If the quotient is a whole number, then 2 and 56,510,072.5 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 | 113,020,145 | |
| -1 | -113,020,145 |
Now, we try dividing 113,020,145 by 3:
113,020,145 ÷ 3 = 37,673,381.6667
If the quotient is a whole number, then 3 and 37,673,381.6667 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 | 113,020,145 | |
| -1 | -113,020,145 |
Let's try dividing by 4:
113,020,145 ÷ 4 = 28,255,036.25
If the quotient is a whole number, then 4 and 28,255,036.25 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 | 113,020,145 | |
| -1 | 113,020,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 233 | 1,165 | 1,631 | 8,155 | 13,859 | 69,295 | 97,013 | 485,065 | 3,229,147 | 16,145,735 | 22,604,029 | 113,020,145 |
| -1 | -5 | -7 | -35 | -233 | -1,165 | -1,631 | -8,155 | -13,859 | -69,295 | -97,013 | -485,065 | -3,229,147 | -16,145,735 | -22,604,029 | -113,020,145 |
