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 9,220,579, 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 | 9,220,579 | |
| -1 | -9,220,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,220,579.
Example:
1 x 9,220,579 = 9,220,579
and
-1 x -9,220,579 = 9,220,579
Notice both answers equal 9,220,579
With that explanation out of the way, let's continue. Next, we take the number 9,220,579 and divide it by 2:
9,220,579 ÷ 2 = 4,610,289.5
If the quotient is a whole number, then 2 and 4,610,289.5 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 | 9,220,579 | |
| -1 | -9,220,579 |
Now, we try dividing 9,220,579 by 3:
9,220,579 ÷ 3 = 3,073,526.3333
If the quotient is a whole number, then 3 and 3,073,526.3333 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 | 9,220,579 | |
| -1 | -9,220,579 |
Let's try dividing by 4:
9,220,579 ÷ 4 = 2,305,144.75
If the quotient is a whole number, then 4 and 2,305,144.75 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 | 9,220,579 | |
| -1 | 9,220,579 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 59 | 317 | 493 | 1,003 | 1,711 | 5,389 | 9,193 | 18,703 | 29,087 | 156,281 | 317,951 | 542,387 | 9,220,579 |
| -1 | -17 | -29 | -59 | -317 | -493 | -1,003 | -1,711 | -5,389 | -9,193 | -18,703 | -29,087 | -156,281 | -317,951 | -542,387 | -9,220,579 |
