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 235,454,315, 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 | 235,454,315 | |
| -1 | -235,454,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,454,315.
Example:
1 x 235,454,315 = 235,454,315
and
-1 x -235,454,315 = 235,454,315
Notice both answers equal 235,454,315
With that explanation out of the way, let's continue. Next, we take the number 235,454,315 and divide it by 2:
235,454,315 ÷ 2 = 117,727,157.5
If the quotient is a whole number, then 2 and 117,727,157.5 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 | 235,454,315 | |
| -1 | -235,454,315 |
Now, we try dividing 235,454,315 by 3:
235,454,315 ÷ 3 = 78,484,771.6667
If the quotient is a whole number, then 3 and 78,484,771.6667 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 | 235,454,315 | |
| -1 | -235,454,315 |
Let's try dividing by 4:
235,454,315 ÷ 4 = 58,863,578.75
If the quotient is a whole number, then 4 and 58,863,578.75 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 | 235,454,315 | |
| -1 | 235,454,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 163 | 251 | 815 | 1,151 | 1,255 | 5,755 | 40,913 | 187,613 | 204,565 | 288,901 | 938,065 | 1,444,505 | 47,090,863 | 235,454,315 |
| -1 | -5 | -163 | -251 | -815 | -1,151 | -1,255 | -5,755 | -40,913 | -187,613 | -204,565 | -288,901 | -938,065 | -1,444,505 | -47,090,863 | -235,454,315 |
