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 1,270,045, 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 | 1,270,045 | |
| -1 | -1,270,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,270,045.
Example:
1 x 1,270,045 = 1,270,045
and
-1 x -1,270,045 = 1,270,045
Notice both answers equal 1,270,045
With that explanation out of the way, let's continue. Next, we take the number 1,270,045 and divide it by 2:
1,270,045 ÷ 2 = 635,022.5
If the quotient is a whole number, then 2 and 635,022.5 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 | 1,270,045 | |
| -1 | -1,270,045 |
Now, we try dividing 1,270,045 by 3:
1,270,045 ÷ 3 = 423,348.3333
If the quotient is a whole number, then 3 and 423,348.3333 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 | 1,270,045 | |
| -1 | -1,270,045 |
Let's try dividing by 4:
1,270,045 ÷ 4 = 317,511.25
If the quotient is a whole number, then 4 and 317,511.25 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 | 1,270,045 | |
| -1 | 1,270,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 131 | 277 | 655 | 917 | 1,385 | 1,939 | 4,585 | 9,695 | 36,287 | 181,435 | 254,009 | 1,270,045 |
| -1 | -5 | -7 | -35 | -131 | -277 | -655 | -917 | -1,385 | -1,939 | -4,585 | -9,695 | -36,287 | -181,435 | -254,009 | -1,270,045 |
