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 1,227,265, 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 | 1,227,265 | |
| -1 | -1,227,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,227,265.
Example:
1 x 1,227,265 = 1,227,265
and
-1 x -1,227,265 = 1,227,265
Notice both answers equal 1,227,265
With that explanation out of the way, let's continue. Next, we take the number 1,227,265 and divide it by 2:
1,227,265 ÷ 2 = 613,632.5
If the quotient is a whole number, then 2 and 613,632.5 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 | 1,227,265 | |
| -1 | -1,227,265 |
Now, we try dividing 1,227,265 by 3:
1,227,265 ÷ 3 = 409,088.3333
If the quotient is a whole number, then 3 and 409,088.3333 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 | 1,227,265 | |
| -1 | -1,227,265 |
Let's try dividing by 4:
1,227,265 ÷ 4 = 306,816.25
If the quotient is a whole number, then 4 and 306,816.25 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 | 1,227,265 | |
| -1 | 1,227,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 79 | 239 | 395 | 1,027 | 1,195 | 3,107 | 5,135 | 15,535 | 18,881 | 94,405 | 245,453 | 1,227,265 |
| -1 | -5 | -13 | -65 | -79 | -239 | -395 | -1,027 | -1,195 | -3,107 | -5,135 | -15,535 | -18,881 | -94,405 | -245,453 | -1,227,265 |
