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 7,760,039, 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 | 7,760,039 | |
| -1 | -7,760,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,760,039.
Example:
1 x 7,760,039 = 7,760,039
and
-1 x -7,760,039 = 7,760,039
Notice both answers equal 7,760,039
With that explanation out of the way, let's continue. Next, we take the number 7,760,039 and divide it by 2:
7,760,039 ÷ 2 = 3,880,019.5
If the quotient is a whole number, then 2 and 3,880,019.5 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 | 7,760,039 | |
| -1 | -7,760,039 |
Now, we try dividing 7,760,039 by 3:
7,760,039 ÷ 3 = 2,586,679.6667
If the quotient is a whole number, then 3 and 2,586,679.6667 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 | 7,760,039 | |
| -1 | -7,760,039 |
Let's try dividing by 4:
7,760,039 ÷ 4 = 1,940,009.75
If the quotient is a whole number, then 4 and 1,940,009.75 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 | 7,760,039 | |
| -1 | 7,760,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 157 | 161 | 307 | 1,099 | 2,149 | 3,611 | 7,061 | 25,277 | 48,199 | 49,427 | 337,393 | 1,108,577 | 7,760,039 |
| -1 | -7 | -23 | -157 | -161 | -307 | -1,099 | -2,149 | -3,611 | -7,061 | -25,277 | -48,199 | -49,427 | -337,393 | -1,108,577 | -7,760,039 |
