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 235,187,167, 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 | 235,187,167 | |
| -1 | -235,187,167 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,187,167.
Example:
1 x 235,187,167 = 235,187,167
and
-1 x -235,187,167 = 235,187,167
Notice both answers equal 235,187,167
With that explanation out of the way, let's continue. Next, we take the number 235,187,167 and divide it by 2:
235,187,167 ÷ 2 = 117,593,583.5
If the quotient is a whole number, then 2 and 117,593,583.5 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 | 235,187,167 | |
| -1 | -235,187,167 |
Now, we try dividing 235,187,167 by 3:
235,187,167 ÷ 3 = 78,395,722.3333
If the quotient is a whole number, then 3 and 78,395,722.3333 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 | 235,187,167 | |
| -1 | -235,187,167 |
Let's try dividing by 4:
235,187,167 ÷ 4 = 58,796,791.75
If the quotient is a whole number, then 4 and 58,796,791.75 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 | 235,187,167 | |
| -1 | 235,187,167 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 397 | 599 | 989 | 9,131 | 13,777 | 17,071 | 25,757 | 237,803 | 392,633 | 592,411 | 5,469,469 | 10,225,529 | 235,187,167 |
| -1 | -23 | -43 | -397 | -599 | -989 | -9,131 | -13,777 | -17,071 | -25,757 | -237,803 | -392,633 | -592,411 | -5,469,469 | -10,225,529 | -235,187,167 |
