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 3,244,025, 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 | 3,244,025 | |
| -1 | -3,244,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,244,025.
Example:
1 x 3,244,025 = 3,244,025
and
-1 x -3,244,025 = 3,244,025
Notice both answers equal 3,244,025
With that explanation out of the way, let's continue. Next, we take the number 3,244,025 and divide it by 2:
3,244,025 ÷ 2 = 1,622,012.5
If the quotient is a whole number, then 2 and 1,622,012.5 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 | 3,244,025 | |
| -1 | -3,244,025 |
Now, we try dividing 3,244,025 by 3:
3,244,025 ÷ 3 = 1,081,341.6667
If the quotient is a whole number, then 3 and 1,081,341.6667 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 | 3,244,025 | |
| -1 | -3,244,025 |
Let's try dividing by 4:
3,244,025 ÷ 4 = 811,006.25
If the quotient is a whole number, then 4 and 811,006.25 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 | 3,244,025 | |
| -1 | 3,244,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 289 | 425 | 449 | 1,445 | 2,245 | 7,225 | 7,633 | 11,225 | 38,165 | 129,761 | 190,825 | 648,805 | 3,244,025 |
| -1 | -5 | -17 | -25 | -85 | -289 | -425 | -449 | -1,445 | -2,245 | -7,225 | -7,633 | -11,225 | -38,165 | -129,761 | -190,825 | -648,805 | -3,244,025 |
