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 7,960,285, 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 | 7,960,285 | |
| -1 | -7,960,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,960,285.
Example:
1 x 7,960,285 = 7,960,285
and
-1 x -7,960,285 = 7,960,285
Notice both answers equal 7,960,285
With that explanation out of the way, let's continue. Next, we take the number 7,960,285 and divide it by 2:
7,960,285 ÷ 2 = 3,980,142.5
If the quotient is a whole number, then 2 and 3,980,142.5 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 | 7,960,285 | |
| -1 | -7,960,285 |
Now, we try dividing 7,960,285 by 3:
7,960,285 ÷ 3 = 2,653,428.3333
If the quotient is a whole number, then 3 and 2,653,428.3333 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 | 7,960,285 | |
| -1 | -7,960,285 |
Let's try dividing by 4:
7,960,285 ÷ 4 = 1,990,071.25
If the quotient is a whole number, then 4 and 1,990,071.25 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 | 7,960,285 | |
| -1 | 7,960,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 113 | 193 | 365 | 565 | 965 | 8,249 | 14,089 | 21,809 | 41,245 | 70,445 | 109,045 | 1,592,057 | 7,960,285 |
| -1 | -5 | -73 | -113 | -193 | -365 | -565 | -965 | -8,249 | -14,089 | -21,809 | -41,245 | -70,445 | -109,045 | -1,592,057 | -7,960,285 |
