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 2,196,025, 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 | 2,196,025 | |
| -1 | -2,196,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,196,025.
Example:
1 x 2,196,025 = 2,196,025
and
-1 x -2,196,025 = 2,196,025
Notice both answers equal 2,196,025
With that explanation out of the way, let's continue. Next, we take the number 2,196,025 and divide it by 2:
2,196,025 ÷ 2 = 1,098,012.5
If the quotient is a whole number, then 2 and 1,098,012.5 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 | 2,196,025 | |
| -1 | -2,196,025 |
Now, we try dividing 2,196,025 by 3:
2,196,025 ÷ 3 = 732,008.3333
If the quotient is a whole number, then 3 and 732,008.3333 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 | 2,196,025 | |
| -1 | -2,196,025 |
Let's try dividing by 4:
2,196,025 ÷ 4 = 549,006.25
If the quotient is a whole number, then 4 and 549,006.25 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 | 2,196,025 | |
| -1 | 2,196,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 65 | 145 | 233 | 325 | 377 | 725 | 1,165 | 1,885 | 3,029 | 5,825 | 6,757 | 9,425 | 15,145 | 33,785 | 75,725 | 87,841 | 168,925 | 439,205 | 2,196,025 |
| -1 | -5 | -13 | -25 | -29 | -65 | -145 | -233 | -325 | -377 | -725 | -1,165 | -1,885 | -3,029 | -5,825 | -6,757 | -9,425 | -15,145 | -33,785 | -75,725 | -87,841 | -168,925 | -439,205 | -2,196,025 |
