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 3,298,631, 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 | 3,298,631 | |
| -1 | -3,298,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,298,631.
Example:
1 x 3,298,631 = 3,298,631
and
-1 x -3,298,631 = 3,298,631
Notice both answers equal 3,298,631
With that explanation out of the way, let's continue. Next, we take the number 3,298,631 and divide it by 2:
3,298,631 ÷ 2 = 1,649,315.5
If the quotient is a whole number, then 2 and 1,649,315.5 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 | 3,298,631 | |
| -1 | -3,298,631 |
Now, we try dividing 3,298,631 by 3:
3,298,631 ÷ 3 = 1,099,543.6667
If the quotient is a whole number, then 3 and 1,099,543.6667 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 | 3,298,631 | |
| -1 | -3,298,631 |
Let's try dividing by 4:
3,298,631 ÷ 4 = 824,657.75
If the quotient is a whole number, then 4 and 824,657.75 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 | 3,298,631 | |
| -1 | 3,298,631 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 59 | 163 | 343 | 413 | 1,141 | 2,891 | 7,987 | 9,617 | 20,237 | 55,909 | 67,319 | 471,233 | 3,298,631 |
| -1 | -7 | -49 | -59 | -163 | -343 | -413 | -1,141 | -2,891 | -7,987 | -9,617 | -20,237 | -55,909 | -67,319 | -471,233 | -3,298,631 |
