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 7,984,955, 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 | 7,984,955 | |
| -1 | -7,984,955 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,984,955.
Example:
1 x 7,984,955 = 7,984,955
and
-1 x -7,984,955 = 7,984,955
Notice both answers equal 7,984,955
With that explanation out of the way, let's continue. Next, we take the number 7,984,955 and divide it by 2:
7,984,955 ÷ 2 = 3,992,477.5
If the quotient is a whole number, then 2 and 3,992,477.5 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 | 7,984,955 | |
| -1 | -7,984,955 |
Now, we try dividing 7,984,955 by 3:
7,984,955 ÷ 3 = 2,661,651.6667
If the quotient is a whole number, then 3 and 2,661,651.6667 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 | 7,984,955 | |
| -1 | -7,984,955 |
Let's try dividing by 4:
7,984,955 ÷ 4 = 1,996,238.75
If the quotient is a whole number, then 4 and 1,996,238.75 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 | 7,984,955 | |
| -1 | 7,984,955 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 3,541 | 17,705 | 38,951 | 145,181 | 194,755 | 725,905 | 1,596,991 | 7,984,955 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -3,541 | -17,705 | -38,951 | -145,181 | -194,755 | -725,905 | -1,596,991 | -7,984,955 |
