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 7,960,277, 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 | 7,960,277 | |
| -1 | -7,960,277 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,960,277.
Example:
1 x 7,960,277 = 7,960,277
and
-1 x -7,960,277 = 7,960,277
Notice both answers equal 7,960,277
With that explanation out of the way, let's continue. Next, we take the number 7,960,277 and divide it by 2:
7,960,277 ÷ 2 = 3,980,138.5
If the quotient is a whole number, then 2 and 3,980,138.5 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 | 7,960,277 | |
| -1 | -7,960,277 |
Now, we try dividing 7,960,277 by 3:
7,960,277 ÷ 3 = 2,653,425.6667
If the quotient is a whole number, then 3 and 2,653,425.6667 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 | 7,960,277 | |
| -1 | -7,960,277 |
Let's try dividing by 4:
7,960,277 ÷ 4 = 1,990,069.25
If the quotient is a whole number, then 4 and 1,990,069.25 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 | 7,960,277 | |
| -1 | 7,960,277 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 79 | 299 | 337 | 1,027 | 1,817 | 4,381 | 7,751 | 23,621 | 26,623 | 100,763 | 346,099 | 612,329 | 7,960,277 |
| -1 | -13 | -23 | -79 | -299 | -337 | -1,027 | -1,817 | -4,381 | -7,751 | -23,621 | -26,623 | -100,763 | -346,099 | -612,329 | -7,960,277 |
