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 7,722,265, 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 | 7,722,265 | |
| -1 | -7,722,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,722,265.
Example:
1 x 7,722,265 = 7,722,265
and
-1 x -7,722,265 = 7,722,265
Notice both answers equal 7,722,265
With that explanation out of the way, let's continue. Next, we take the number 7,722,265 and divide it by 2:
7,722,265 ÷ 2 = 3,861,132.5
If the quotient is a whole number, then 2 and 3,861,132.5 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 | 7,722,265 | |
| -1 | -7,722,265 |
Now, we try dividing 7,722,265 by 3:
7,722,265 ÷ 3 = 2,574,088.3333
If the quotient is a whole number, then 3 and 2,574,088.3333 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 | 7,722,265 | |
| -1 | -7,722,265 |
Let's try dividing by 4:
7,722,265 ÷ 4 = 1,930,566.25
If the quotient is a whole number, then 4 and 1,930,566.25 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 | 7,722,265 | |
| -1 | 7,722,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 551 | 2,755 | 2,803 | 14,015 | 53,257 | 81,287 | 266,285 | 406,435 | 1,544,453 | 7,722,265 |
| -1 | -5 | -19 | -29 | -95 | -145 | -551 | -2,755 | -2,803 | -14,015 | -53,257 | -81,287 | -266,285 | -406,435 | -1,544,453 | -7,722,265 |
