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 7,644,073, 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 | 7,644,073 | |
| -1 | -7,644,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,644,073.
Example:
1 x 7,644,073 = 7,644,073
and
-1 x -7,644,073 = 7,644,073
Notice both answers equal 7,644,073
With that explanation out of the way, let's continue. Next, we take the number 7,644,073 and divide it by 2:
7,644,073 ÷ 2 = 3,822,036.5
If the quotient is a whole number, then 2 and 3,822,036.5 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 | 7,644,073 | |
| -1 | -7,644,073 |
Now, we try dividing 7,644,073 by 3:
7,644,073 ÷ 3 = 2,548,024.3333
If the quotient is a whole number, then 3 and 2,548,024.3333 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 | 7,644,073 | |
| -1 | -7,644,073 |
Let's try dividing by 4:
7,644,073 ÷ 4 = 1,911,018.25
If the quotient is a whole number, then 4 and 1,911,018.25 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 | 7,644,073 | |
| -1 | 7,644,073 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 71 | 151 | 713 | 1,633 | 2,201 | 3,473 | 4,681 | 10,721 | 50,623 | 107,663 | 246,583 | 332,351 | 7,644,073 |
| -1 | -23 | -31 | -71 | -151 | -713 | -1,633 | -2,201 | -3,473 | -4,681 | -10,721 | -50,623 | -107,663 | -246,583 | -332,351 | -7,644,073 |
