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 631,475, 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 | 631,475 | |
| -1 | -631,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 631,475.
Example:
1 x 631,475 = 631,475
and
-1 x -631,475 = 631,475
Notice both answers equal 631,475
With that explanation out of the way, let's continue. Next, we take the number 631,475 and divide it by 2:
631,475 ÷ 2 = 315,737.5
If the quotient is a whole number, then 2 and 315,737.5 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 | 631,475 | |
| -1 | -631,475 |
Now, we try dividing 631,475 by 3:
631,475 ÷ 3 = 210,491.6667
If the quotient is a whole number, then 3 and 210,491.6667 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 | 631,475 | |
| -1 | -631,475 |
Let's try dividing by 4:
631,475 ÷ 4 = 157,868.75
If the quotient is a whole number, then 4 and 157,868.75 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 | 631,475 | |
| -1 | 631,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 65 | 67 | 145 | 325 | 335 | 377 | 725 | 871 | 1,675 | 1,885 | 1,943 | 4,355 | 9,425 | 9,715 | 21,775 | 25,259 | 48,575 | 126,295 | 631,475 |
| -1 | -5 | -13 | -25 | -29 | -65 | -67 | -145 | -325 | -335 | -377 | -725 | -871 | -1,675 | -1,885 | -1,943 | -4,355 | -9,425 | -9,715 | -21,775 | -25,259 | -48,575 | -126,295 | -631,475 |
