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 113,303,203, 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 | 113,303,203 | |
| -1 | -113,303,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,303,203.
Example:
1 x 113,303,203 = 113,303,203
and
-1 x -113,303,203 = 113,303,203
Notice both answers equal 113,303,203
With that explanation out of the way, let's continue. Next, we take the number 113,303,203 and divide it by 2:
113,303,203 ÷ 2 = 56,651,601.5
If the quotient is a whole number, then 2 and 56,651,601.5 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 | 113,303,203 | |
| -1 | -113,303,203 |
Now, we try dividing 113,303,203 by 3:
113,303,203 ÷ 3 = 37,767,734.3333
If the quotient is a whole number, then 3 and 37,767,734.3333 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 | 113,303,203 | |
| -1 | -113,303,203 |
Let's try dividing by 4:
113,303,203 ÷ 4 = 28,325,800.75
If the quotient is a whole number, then 4 and 28,325,800.75 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 | 113,303,203 | |
| -1 | 113,303,203 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 271 | 377 | 1,109 | 3,523 | 7,859 | 14,417 | 32,161 | 102,167 | 300,539 | 418,093 | 3,907,007 | 8,715,631 | 113,303,203 |
| -1 | -13 | -29 | -271 | -377 | -1,109 | -3,523 | -7,859 | -14,417 | -32,161 | -102,167 | -300,539 | -418,093 | -3,907,007 | -8,715,631 | -113,303,203 |
