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 7,927,801, 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 | 7,927,801 | |
| -1 | -7,927,801 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,927,801.
Example:
1 x 7,927,801 = 7,927,801
and
-1 x -7,927,801 = 7,927,801
Notice both answers equal 7,927,801
With that explanation out of the way, let's continue. Next, we take the number 7,927,801 and divide it by 2:
7,927,801 ÷ 2 = 3,963,900.5
If the quotient is a whole number, then 2 and 3,963,900.5 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 | 7,927,801 | |
| -1 | -7,927,801 |
Now, we try dividing 7,927,801 by 3:
7,927,801 ÷ 3 = 2,642,600.3333
If the quotient is a whole number, then 3 and 2,642,600.3333 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 | 7,927,801 | |
| -1 | -7,927,801 |
Let's try dividing by 4:
7,927,801 ÷ 4 = 1,981,950.25
If the quotient is a whole number, then 4 and 1,981,950.25 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 | 7,927,801 | |
| -1 | 7,927,801 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 41 | 161 | 287 | 943 | 1,201 | 6,601 | 8,407 | 27,623 | 49,241 | 193,361 | 344,687 | 1,132,543 | 7,927,801 |
| -1 | -7 | -23 | -41 | -161 | -287 | -943 | -1,201 | -6,601 | -8,407 | -27,623 | -49,241 | -193,361 | -344,687 | -1,132,543 | -7,927,801 |
