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 115,343,033, 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 | 115,343,033 | |
| -1 | -115,343,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,343,033.
Example:
1 x 115,343,033 = 115,343,033
and
-1 x -115,343,033 = 115,343,033
Notice both answers equal 115,343,033
With that explanation out of the way, let's continue. Next, we take the number 115,343,033 and divide it by 2:
115,343,033 ÷ 2 = 57,671,516.5
If the quotient is a whole number, then 2 and 57,671,516.5 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 | 115,343,033 | |
| -1 | -115,343,033 |
Now, we try dividing 115,343,033 by 3:
115,343,033 ÷ 3 = 38,447,677.6667
If the quotient is a whole number, then 3 and 38,447,677.6667 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 | 115,343,033 | |
| -1 | -115,343,033 |
Let's try dividing by 4:
115,343,033 ÷ 4 = 28,835,758.25
If the quotient is a whole number, then 4 and 28,835,758.25 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 | 115,343,033 | |
| -1 | 115,343,033 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 157 | 403 | 1,823 | 2,041 | 4,867 | 23,699 | 56,513 | 63,271 | 286,211 | 734,669 | 3,720,743 | 8,872,541 | 115,343,033 |
| -1 | -13 | -31 | -157 | -403 | -1,823 | -2,041 | -4,867 | -23,699 | -56,513 | -63,271 | -286,211 | -734,669 | -3,720,743 | -8,872,541 | -115,343,033 |
