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 7,688,369, 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 | 7,688,369 | |
| -1 | -7,688,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,688,369.
Example:
1 x 7,688,369 = 7,688,369
and
-1 x -7,688,369 = 7,688,369
Notice both answers equal 7,688,369
With that explanation out of the way, let's continue. Next, we take the number 7,688,369 and divide it by 2:
7,688,369 ÷ 2 = 3,844,184.5
If the quotient is a whole number, then 2 and 3,844,184.5 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 | 7,688,369 | |
| -1 | -7,688,369 |
Now, we try dividing 7,688,369 by 3:
7,688,369 ÷ 3 = 2,562,789.6667
If the quotient is a whole number, then 3 and 2,562,789.6667 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 | 7,688,369 | |
| -1 | -7,688,369 |
Let's try dividing by 4:
7,688,369 ÷ 4 = 1,922,092.25
If the quotient is a whole number, then 4 and 1,922,092.25 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 | 7,688,369 | |
| -1 | 7,688,369 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 221 | 247 | 323 | 1,831 | 4,199 | 23,803 | 31,127 | 34,789 | 404,651 | 452,257 | 591,413 | 7,688,369 |
| -1 | -13 | -17 | -19 | -221 | -247 | -323 | -1,831 | -4,199 | -23,803 | -31,127 | -34,789 | -404,651 | -452,257 | -591,413 | -7,688,369 |
