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 7,580,965, 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 | 7,580,965 | |
| -1 | -7,580,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,580,965.
Example:
1 x 7,580,965 = 7,580,965
and
-1 x -7,580,965 = 7,580,965
Notice both answers equal 7,580,965
With that explanation out of the way, let's continue. Next, we take the number 7,580,965 and divide it by 2:
7,580,965 ÷ 2 = 3,790,482.5
If the quotient is a whole number, then 2 and 3,790,482.5 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 | 7,580,965 | |
| -1 | -7,580,965 |
Now, we try dividing 7,580,965 by 3:
7,580,965 ÷ 3 = 2,526,988.3333
If the quotient is a whole number, then 3 and 2,526,988.3333 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 | 7,580,965 | |
| -1 | -7,580,965 |
Let's try dividing by 4:
7,580,965 ÷ 4 = 1,895,241.25
If the quotient is a whole number, then 4 and 1,895,241.25 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 | 7,580,965 | |
| -1 | 7,580,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 167 | 835 | 1,169 | 1,297 | 5,845 | 6,485 | 9,079 | 45,395 | 216,599 | 1,082,995 | 1,516,193 | 7,580,965 |
| -1 | -5 | -7 | -35 | -167 | -835 | -1,169 | -1,297 | -5,845 | -6,485 | -9,079 | -45,395 | -216,599 | -1,082,995 | -1,516,193 | -7,580,965 |
