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 3,201,253, 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 | 3,201,253 | |
| -1 | -3,201,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,201,253.
Example:
1 x 3,201,253 = 3,201,253
and
-1 x -3,201,253 = 3,201,253
Notice both answers equal 3,201,253
With that explanation out of the way, let's continue. Next, we take the number 3,201,253 and divide it by 2:
3,201,253 ÷ 2 = 1,600,626.5
If the quotient is a whole number, then 2 and 1,600,626.5 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 | 3,201,253 | |
| -1 | -3,201,253 |
Now, we try dividing 3,201,253 by 3:
3,201,253 ÷ 3 = 1,067,084.3333
If the quotient is a whole number, then 3 and 1,067,084.3333 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 | 3,201,253 | |
| -1 | -3,201,253 |
Let's try dividing by 4:
3,201,253 ÷ 4 = 800,313.25
If the quotient is a whole number, then 4 and 800,313.25 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 | 3,201,253 | |
| -1 | 3,201,253 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 53 | 187 | 209 | 289 | 323 | 583 | 901 | 1,007 | 3,179 | 3,553 | 5,491 | 9,911 | 11,077 | 15,317 | 17,119 | 60,401 | 168,487 | 188,309 | 291,023 | 3,201,253 |
| -1 | -11 | -17 | -19 | -53 | -187 | -209 | -289 | -323 | -583 | -901 | -1,007 | -3,179 | -3,553 | -5,491 | -9,911 | -11,077 | -15,317 | -17,119 | -60,401 | -168,487 | -188,309 | -291,023 | -3,201,253 |
