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 233,873,315, 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 | 233,873,315 | |
| -1 | -233,873,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,873,315.
Example:
1 x 233,873,315 = 233,873,315
and
-1 x -233,873,315 = 233,873,315
Notice both answers equal 233,873,315
With that explanation out of the way, let's continue. Next, we take the number 233,873,315 and divide it by 2:
233,873,315 ÷ 2 = 116,936,657.5
If the quotient is a whole number, then 2 and 116,936,657.5 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 | 233,873,315 | |
| -1 | -233,873,315 |
Now, we try dividing 233,873,315 by 3:
233,873,315 ÷ 3 = 77,957,771.6667
If the quotient is a whole number, then 3 and 77,957,771.6667 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 | 233,873,315 | |
| -1 | -233,873,315 |
Let's try dividing by 4:
233,873,315 ÷ 4 = 58,468,328.75
If the quotient is a whole number, then 4 and 58,468,328.75 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 | 233,873,315 | |
| -1 | 233,873,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 156,437 | 782,185 | 2,033,681 | 3,598,051 | 10,168,405 | 17,990,255 | 46,774,663 | 233,873,315 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -156,437 | -782,185 | -2,033,681 | -3,598,051 | -10,168,405 | -17,990,255 | -46,774,663 | -233,873,315 |
