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 17,223,073, 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 | 17,223,073 | |
| -1 | -17,223,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,223,073.
Example:
1 x 17,223,073 = 17,223,073
and
-1 x -17,223,073 = 17,223,073
Notice both answers equal 17,223,073
With that explanation out of the way, let's continue. Next, we take the number 17,223,073 and divide it by 2:
17,223,073 ÷ 2 = 8,611,536.5
If the quotient is a whole number, then 2 and 8,611,536.5 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 | 17,223,073 | |
| -1 | -17,223,073 |
Now, we try dividing 17,223,073 by 3:
17,223,073 ÷ 3 = 5,741,024.3333
If the quotient is a whole number, then 3 and 5,741,024.3333 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 | 17,223,073 | |
| -1 | -17,223,073 |
Let's try dividing by 4:
17,223,073 ÷ 4 = 4,305,768.25
If the quotient is a whole number, then 4 and 4,305,768.25 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 | 17,223,073 | |
| -1 | 17,223,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 139 | 217 | 571 | 973 | 3,997 | 4,309 | 17,701 | 30,163 | 79,369 | 123,907 | 555,583 | 2,460,439 | 17,223,073 |
| -1 | -7 | -31 | -139 | -217 | -571 | -973 | -3,997 | -4,309 | -17,701 | -30,163 | -79,369 | -123,907 | -555,583 | -2,460,439 | -17,223,073 |
