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 7,955,255, 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 | 7,955,255 | |
| -1 | -7,955,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,955,255.
Example:
1 x 7,955,255 = 7,955,255
and
-1 x -7,955,255 = 7,955,255
Notice both answers equal 7,955,255
With that explanation out of the way, let's continue. Next, we take the number 7,955,255 and divide it by 2:
7,955,255 ÷ 2 = 3,977,627.5
If the quotient is a whole number, then 2 and 3,977,627.5 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 | 7,955,255 | |
| -1 | -7,955,255 |
Now, we try dividing 7,955,255 by 3:
7,955,255 ÷ 3 = 2,651,751.6667
If the quotient is a whole number, then 3 and 2,651,751.6667 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 | 7,955,255 | |
| -1 | -7,955,255 |
Let's try dividing by 4:
7,955,255 ÷ 4 = 1,988,813.75
If the quotient is a whole number, then 4 and 1,988,813.75 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 | 7,955,255 | |
| -1 | 7,955,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 20,663 | 103,315 | 144,641 | 227,293 | 723,205 | 1,136,465 | 1,591,051 | 7,955,255 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -20,663 | -103,315 | -144,641 | -227,293 | -723,205 | -1,136,465 | -1,591,051 | -7,955,255 |
