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 235,313,045, 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 | 235,313,045 | |
| -1 | -235,313,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,313,045.
Example:
1 x 235,313,045 = 235,313,045
and
-1 x -235,313,045 = 235,313,045
Notice both answers equal 235,313,045
With that explanation out of the way, let's continue. Next, we take the number 235,313,045 and divide it by 2:
235,313,045 ÷ 2 = 117,656,522.5
If the quotient is a whole number, then 2 and 117,656,522.5 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 | 235,313,045 | |
| -1 | -235,313,045 |
Now, we try dividing 235,313,045 by 3:
235,313,045 ÷ 3 = 78,437,681.6667
If the quotient is a whole number, then 3 and 78,437,681.6667 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 | 235,313,045 | |
| -1 | -235,313,045 |
Let's try dividing by 4:
235,313,045 ÷ 4 = 58,828,261.25
If the quotient is a whole number, then 4 and 58,828,261.25 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 | 235,313,045 | |
| -1 | 235,313,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 63,857 | 319,285 | 702,427 | 3,512,135 | 4,278,419 | 21,392,095 | 47,062,609 | 235,313,045 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -63,857 | -319,285 | -702,427 | -3,512,135 | -4,278,419 | -21,392,095 | -47,062,609 | -235,313,045 |
