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 7,225,673, 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 | 7,225,673 | |
| -1 | -7,225,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,225,673.
Example:
1 x 7,225,673 = 7,225,673
and
-1 x -7,225,673 = 7,225,673
Notice both answers equal 7,225,673
With that explanation out of the way, let's continue. Next, we take the number 7,225,673 and divide it by 2:
7,225,673 ÷ 2 = 3,612,836.5
If the quotient is a whole number, then 2 and 3,612,836.5 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 | 7,225,673 | |
| -1 | -7,225,673 |
Now, we try dividing 7,225,673 by 3:
7,225,673 ÷ 3 = 2,408,557.6667
If the quotient is a whole number, then 3 and 2,408,557.6667 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 | 7,225,673 | |
| -1 | -7,225,673 |
Let's try dividing by 4:
7,225,673 ÷ 4 = 1,806,418.25
If the quotient is a whole number, then 4 and 1,806,418.25 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 | 7,225,673 | |
| -1 | 7,225,673 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 271 | 293 | 1,897 | 2,051 | 3,523 | 3,809 | 24,661 | 26,663 | 79,403 | 555,821 | 1,032,239 | 7,225,673 |
| -1 | -7 | -13 | -91 | -271 | -293 | -1,897 | -2,051 | -3,523 | -3,809 | -24,661 | -26,663 | -79,403 | -555,821 | -1,032,239 | -7,225,673 |
