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 3,172,325, 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 | 3,172,325 | |
| -1 | -3,172,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,172,325.
Example:
1 x 3,172,325 = 3,172,325
and
-1 x -3,172,325 = 3,172,325
Notice both answers equal 3,172,325
With that explanation out of the way, let's continue. Next, we take the number 3,172,325 and divide it by 2:
3,172,325 ÷ 2 = 1,586,162.5
If the quotient is a whole number, then 2 and 1,586,162.5 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 | 3,172,325 | |
| -1 | -3,172,325 |
Now, we try dividing 3,172,325 by 3:
3,172,325 ÷ 3 = 1,057,441.6667
If the quotient is a whole number, then 3 and 1,057,441.6667 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 | 3,172,325 | |
| -1 | -3,172,325 |
Let's try dividing by 4:
3,172,325 ÷ 4 = 793,081.25
If the quotient is a whole number, then 4 and 793,081.25 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 | 3,172,325 | |
| -1 | 3,172,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 43 | 65 | 215 | 227 | 325 | 559 | 1,075 | 1,135 | 2,795 | 2,951 | 5,675 | 9,761 | 13,975 | 14,755 | 48,805 | 73,775 | 126,893 | 244,025 | 634,465 | 3,172,325 |
| -1 | -5 | -13 | -25 | -43 | -65 | -215 | -227 | -325 | -559 | -1,075 | -1,135 | -2,795 | -2,951 | -5,675 | -9,761 | -13,975 | -14,755 | -48,805 | -73,775 | -126,893 | -244,025 | -634,465 | -3,172,325 |
