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 315,425, 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 | 315,425 | |
| -1 | -315,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 315,425.
Example:
1 x 315,425 = 315,425
and
-1 x -315,425 = 315,425
Notice both answers equal 315,425
With that explanation out of the way, let's continue. Next, we take the number 315,425 and divide it by 2:
315,425 ÷ 2 = 157,712.5
If the quotient is a whole number, then 2 and 157,712.5 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 | 315,425 | |
| -1 | -315,425 |
Now, we try dividing 315,425 by 3:
315,425 ÷ 3 = 105,141.6667
If the quotient is a whole number, then 3 and 105,141.6667 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 | 315,425 | |
| -1 | -315,425 |
Let's try dividing by 4:
315,425 ÷ 4 = 78,856.25
If the quotient is a whole number, then 4 and 78,856.25 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 | 315,425 | |
| -1 | 315,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 37 | 55 | 155 | 185 | 275 | 341 | 407 | 775 | 925 | 1,147 | 1,705 | 2,035 | 5,735 | 8,525 | 10,175 | 12,617 | 28,675 | 63,085 | 315,425 |
| -1 | -5 | -11 | -25 | -31 | -37 | -55 | -155 | -185 | -275 | -341 | -407 | -775 | -925 | -1,147 | -1,705 | -2,035 | -5,735 | -8,525 | -10,175 | -12,617 | -28,675 | -63,085 | -315,425 |
