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 5,220,655, 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 | 5,220,655 | |
| -1 | -5,220,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,220,655.
Example:
1 x 5,220,655 = 5,220,655
and
-1 x -5,220,655 = 5,220,655
Notice both answers equal 5,220,655
With that explanation out of the way, let's continue. Next, we take the number 5,220,655 and divide it by 2:
5,220,655 ÷ 2 = 2,610,327.5
If the quotient is a whole number, then 2 and 2,610,327.5 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 | 5,220,655 | |
| -1 | -5,220,655 |
Now, we try dividing 5,220,655 by 3:
5,220,655 ÷ 3 = 1,740,218.3333
If the quotient is a whole number, then 3 and 1,740,218.3333 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 | 5,220,655 | |
| -1 | -5,220,655 |
Let's try dividing by 4:
5,220,655 ÷ 4 = 1,305,163.75
If the quotient is a whole number, then 4 and 1,305,163.75 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 | 5,220,655 | |
| -1 | 5,220,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 4,127 | 20,635 | 45,397 | 94,921 | 226,985 | 474,605 | 1,044,131 | 5,220,655 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -4,127 | -20,635 | -45,397 | -94,921 | -226,985 | -474,605 | -1,044,131 | -5,220,655 |
