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 5,580,497, 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 | 5,580,497 | |
| -1 | -5,580,497 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,580,497.
Example:
1 x 5,580,497 = 5,580,497
and
-1 x -5,580,497 = 5,580,497
Notice both answers equal 5,580,497
With that explanation out of the way, let's continue. Next, we take the number 5,580,497 and divide it by 2:
5,580,497 ÷ 2 = 2,790,248.5
If the quotient is a whole number, then 2 and 2,790,248.5 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 | 5,580,497 | |
| -1 | -5,580,497 |
Now, we try dividing 5,580,497 by 3:
5,580,497 ÷ 3 = 1,860,165.6667
If the quotient is a whole number, then 3 and 1,860,165.6667 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 | 5,580,497 | |
| -1 | -5,580,497 |
Let's try dividing by 4:
5,580,497 ÷ 4 = 1,395,124.25
If the quotient is a whole number, then 4 and 1,395,124.25 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 | 5,580,497 | |
| -1 | 5,580,497 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 67 | 149 | 559 | 871 | 1,937 | 2,881 | 6,407 | 9,983 | 37,453 | 83,291 | 129,779 | 429,269 | 5,580,497 |
| -1 | -13 | -43 | -67 | -149 | -559 | -871 | -1,937 | -2,881 | -6,407 | -9,983 | -37,453 | -83,291 | -129,779 | -429,269 | -5,580,497 |
