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 8,220,289, 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 | 8,220,289 | |
| -1 | -8,220,289 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,220,289.
Example:
1 x 8,220,289 = 8,220,289
and
-1 x -8,220,289 = 8,220,289
Notice both answers equal 8,220,289
With that explanation out of the way, let's continue. Next, we take the number 8,220,289 and divide it by 2:
8,220,289 ÷ 2 = 4,110,144.5
If the quotient is a whole number, then 2 and 4,110,144.5 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 | 8,220,289 | |
| -1 | -8,220,289 |
Now, we try dividing 8,220,289 by 3:
8,220,289 ÷ 3 = 2,740,096.3333
If the quotient is a whole number, then 3 and 2,740,096.3333 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 | 8,220,289 | |
| -1 | -8,220,289 |
Let's try dividing by 4:
8,220,289 ÷ 4 = 2,055,072.25
If the quotient is a whole number, then 4 and 2,055,072.25 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 | 8,220,289 | |
| -1 | 8,220,289 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 101 | 151 | 539 | 707 | 1,057 | 1,111 | 1,661 | 4,949 | 7,399 | 7,777 | 11,627 | 15,251 | 54,439 | 81,389 | 106,757 | 167,761 | 747,299 | 1,174,327 | 8,220,289 |
| -1 | -7 | -11 | -49 | -77 | -101 | -151 | -539 | -707 | -1,057 | -1,111 | -1,661 | -4,949 | -7,399 | -7,777 | -11,627 | -15,251 | -54,439 | -81,389 | -106,757 | -167,761 | -747,299 | -1,174,327 | -8,220,289 |
