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 1,015,223, 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 | 1,015,223 | |
| -1 | -1,015,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,015,223.
Example:
1 x 1,015,223 = 1,015,223
and
-1 x -1,015,223 = 1,015,223
Notice both answers equal 1,015,223
With that explanation out of the way, let's continue. Next, we take the number 1,015,223 and divide it by 2:
1,015,223 ÷ 2 = 507,611.5
If the quotient is a whole number, then 2 and 507,611.5 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 | 1,015,223 | |
| -1 | -1,015,223 |
Now, we try dividing 1,015,223 by 3:
1,015,223 ÷ 3 = 338,407.6667
If the quotient is a whole number, then 3 and 338,407.6667 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 | 1,015,223 | |
| -1 | -1,015,223 |
Let's try dividing by 4:
1,015,223 ÷ 4 = 253,805.75
If the quotient is a whole number, then 4 and 253,805.75 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 | 1,015,223 | |
| -1 | 1,015,223 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 61 | 89 | 187 | 671 | 979 | 1,037 | 1,513 | 5,429 | 11,407 | 16,643 | 59,719 | 92,293 | 1,015,223 |
| -1 | -11 | -17 | -61 | -89 | -187 | -671 | -979 | -1,037 | -1,513 | -5,429 | -11,407 | -16,643 | -59,719 | -92,293 | -1,015,223 |
