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 1,588,223, 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 | 1,588,223 | |
| -1 | -1,588,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,588,223.
Example:
1 x 1,588,223 = 1,588,223
and
-1 x -1,588,223 = 1,588,223
Notice both answers equal 1,588,223
With that explanation out of the way, let's continue. Next, we take the number 1,588,223 and divide it by 2:
1,588,223 ÷ 2 = 794,111.5
If the quotient is a whole number, then 2 and 794,111.5 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 | 1,588,223 | |
| -1 | -1,588,223 |
Now, we try dividing 1,588,223 by 3:
1,588,223 ÷ 3 = 529,407.6667
If the quotient is a whole number, then 3 and 529,407.6667 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 | 1,588,223 | |
| -1 | -1,588,223 |
Let's try dividing by 4:
1,588,223 ÷ 4 = 397,055.75
If the quotient is a whole number, then 4 and 397,055.75 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 | 1,588,223 | |
| -1 | 1,588,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 563 | 2,821 | 3,941 | 7,319 | 17,453 | 51,233 | 122,171 | 226,889 | 1,588,223 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -563 | -2,821 | -3,941 | -7,319 | -17,453 | -51,233 | -122,171 | -226,889 | -1,588,223 |
