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 7,315,055, 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 | 7,315,055 | |
| -1 | -7,315,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,315,055.
Example:
1 x 7,315,055 = 7,315,055
and
-1 x -7,315,055 = 7,315,055
Notice both answers equal 7,315,055
With that explanation out of the way, let's continue. Next, we take the number 7,315,055 and divide it by 2:
7,315,055 ÷ 2 = 3,657,527.5
If the quotient is a whole number, then 2 and 3,657,527.5 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 | 7,315,055 | |
| -1 | -7,315,055 |
Now, we try dividing 7,315,055 by 3:
7,315,055 ÷ 3 = 2,438,351.6667
If the quotient is a whole number, then 3 and 2,438,351.6667 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 | 7,315,055 | |
| -1 | -7,315,055 |
Let's try dividing by 4:
7,315,055 ÷ 4 = 1,828,763.75
If the quotient is a whole number, then 4 and 1,828,763.75 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 | 7,315,055 | |
| -1 | 7,315,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 113 | 121 | 535 | 565 | 605 | 1,177 | 1,243 | 5,885 | 6,215 | 12,091 | 12,947 | 13,673 | 60,455 | 64,735 | 68,365 | 133,001 | 665,005 | 1,463,011 | 7,315,055 |
| -1 | -5 | -11 | -55 | -107 | -113 | -121 | -535 | -565 | -605 | -1,177 | -1,243 | -5,885 | -6,215 | -12,091 | -12,947 | -13,673 | -60,455 | -64,735 | -68,365 | -133,001 | -665,005 | -1,463,011 | -7,315,055 |
