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 3,250,505, 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 | 3,250,505 | |
| -1 | -3,250,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,250,505.
Example:
1 x 3,250,505 = 3,250,505
and
-1 x -3,250,505 = 3,250,505
Notice both answers equal 3,250,505
With that explanation out of the way, let's continue. Next, we take the number 3,250,505 and divide it by 2:
3,250,505 ÷ 2 = 1,625,252.5
If the quotient is a whole number, then 2 and 1,625,252.5 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 | 3,250,505 | |
| -1 | -3,250,505 |
Now, we try dividing 3,250,505 by 3:
3,250,505 ÷ 3 = 1,083,501.6667
If the quotient is a whole number, then 3 and 1,083,501.6667 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 | 3,250,505 | |
| -1 | -3,250,505 |
Let's try dividing by 4:
3,250,505 ÷ 4 = 812,626.25
If the quotient is a whole number, then 4 and 812,626.25 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 | 3,250,505 | |
| -1 | 3,250,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 67 | 155 | 313 | 335 | 1,565 | 2,077 | 9,703 | 10,385 | 20,971 | 48,515 | 104,855 | 650,101 | 3,250,505 |
| -1 | -5 | -31 | -67 | -155 | -313 | -335 | -1,565 | -2,077 | -9,703 | -10,385 | -20,971 | -48,515 | -104,855 | -650,101 | -3,250,505 |
