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 1,268,323, 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 | 1,268,323 | |
| -1 | -1,268,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,268,323.
Example:
1 x 1,268,323 = 1,268,323
and
-1 x -1,268,323 = 1,268,323
Notice both answers equal 1,268,323
With that explanation out of the way, let's continue. Next, we take the number 1,268,323 and divide it by 2:
1,268,323 ÷ 2 = 634,161.5
If the quotient is a whole number, then 2 and 634,161.5 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 | 1,268,323 | |
| -1 | -1,268,323 |
Now, we try dividing 1,268,323 by 3:
1,268,323 ÷ 3 = 422,774.3333
If the quotient is a whole number, then 3 and 422,774.3333 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 | 1,268,323 | |
| -1 | -1,268,323 |
Let's try dividing by 4:
1,268,323 ÷ 4 = 317,080.75
If the quotient is a whole number, then 4 and 317,080.75 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 | 1,268,323 | |
| -1 | 1,268,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 59 | 83 | 259 | 413 | 581 | 2,183 | 3,071 | 4,897 | 15,281 | 21,497 | 34,279 | 181,189 | 1,268,323 |
| -1 | -7 | -37 | -59 | -83 | -259 | -413 | -581 | -2,183 | -3,071 | -4,897 | -15,281 | -21,497 | -34,279 | -181,189 | -1,268,323 |
