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 3,132,335, 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 | 3,132,335 | |
| -1 | -3,132,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,132,335.
Example:
1 x 3,132,335 = 3,132,335
and
-1 x -3,132,335 = 3,132,335
Notice both answers equal 3,132,335
With that explanation out of the way, let's continue. Next, we take the number 3,132,335 and divide it by 2:
3,132,335 ÷ 2 = 1,566,167.5
If the quotient is a whole number, then 2 and 1,566,167.5 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 | 3,132,335 | |
| -1 | -3,132,335 |
Now, we try dividing 3,132,335 by 3:
3,132,335 ÷ 3 = 1,044,111.6667
If the quotient is a whole number, then 3 and 1,044,111.6667 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 | 3,132,335 | |
| -1 | -3,132,335 |
Let's try dividing by 4:
3,132,335 ÷ 4 = 783,083.75
If the quotient is a whole number, then 4 and 783,083.75 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 | 3,132,335 | |
| -1 | 3,132,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 857 | 3,655 | 4,285 | 14,569 | 36,851 | 72,845 | 184,255 | 626,467 | 3,132,335 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -857 | -3,655 | -4,285 | -14,569 | -36,851 | -72,845 | -184,255 | -626,467 | -3,132,335 |
