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 631,925, 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 | 631,925 | |
| -1 | -631,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 631,925.
Example:
1 x 631,925 = 631,925
and
-1 x -631,925 = 631,925
Notice both answers equal 631,925
With that explanation out of the way, let's continue. Next, we take the number 631,925 and divide it by 2:
631,925 ÷ 2 = 315,962.5
If the quotient is a whole number, then 2 and 315,962.5 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 | 631,925 | |
| -1 | -631,925 |
Now, we try dividing 631,925 by 3:
631,925 ÷ 3 = 210,641.6667
If the quotient is a whole number, then 3 and 210,641.6667 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 | 631,925 | |
| -1 | -631,925 |
Let's try dividing by 4:
631,925 ÷ 4 = 157,981.25
If the quotient is a whole number, then 4 and 157,981.25 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 | 631,925 | |
| -1 | 631,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 25 | 35 | 115 | 157 | 161 | 175 | 575 | 785 | 805 | 1,099 | 3,611 | 3,925 | 4,025 | 5,495 | 18,055 | 25,277 | 27,475 | 90,275 | 126,385 | 631,925 |
| -1 | -5 | -7 | -23 | -25 | -35 | -115 | -157 | -161 | -175 | -575 | -785 | -805 | -1,099 | -3,611 | -3,925 | -4,025 | -5,495 | -18,055 | -25,277 | -27,475 | -90,275 | -126,385 | -631,925 |
