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 7,670,165, 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 | 7,670,165 | |
| -1 | -7,670,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,670,165.
Example:
1 x 7,670,165 = 7,670,165
and
-1 x -7,670,165 = 7,670,165
Notice both answers equal 7,670,165
With that explanation out of the way, let's continue. Next, we take the number 7,670,165 and divide it by 2:
7,670,165 ÷ 2 = 3,835,082.5
If the quotient is a whole number, then 2 and 3,835,082.5 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 | 7,670,165 | |
| -1 | -7,670,165 |
Now, we try dividing 7,670,165 by 3:
7,670,165 ÷ 3 = 2,556,721.6667
If the quotient is a whole number, then 3 and 2,556,721.6667 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 | 7,670,165 | |
| -1 | -7,670,165 |
Let's try dividing by 4:
7,670,165 ÷ 4 = 1,917,541.25
If the quotient is a whole number, then 4 and 1,917,541.25 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 | 7,670,165 | |
| -1 | 7,670,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 127 | 235 | 257 | 635 | 1,285 | 5,969 | 12,079 | 29,845 | 32,639 | 60,395 | 163,195 | 1,534,033 | 7,670,165 |
| -1 | -5 | -47 | -127 | -235 | -257 | -635 | -1,285 | -5,969 | -12,079 | -29,845 | -32,639 | -60,395 | -163,195 | -1,534,033 | -7,670,165 |
