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 8,970,065, 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 | 8,970,065 | |
| -1 | -8,970,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,970,065.
Example:
1 x 8,970,065 = 8,970,065
and
-1 x -8,970,065 = 8,970,065
Notice both answers equal 8,970,065
With that explanation out of the way, let's continue. Next, we take the number 8,970,065 and divide it by 2:
8,970,065 ÷ 2 = 4,485,032.5
If the quotient is a whole number, then 2 and 4,485,032.5 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 | 8,970,065 | |
| -1 | -8,970,065 |
Now, we try dividing 8,970,065 by 3:
8,970,065 ÷ 3 = 2,990,021.6667
If the quotient is a whole number, then 3 and 2,990,021.6667 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 | 8,970,065 | |
| -1 | -8,970,065 |
Let's try dividing by 4:
8,970,065 ÷ 4 = 2,242,516.25
If the quotient is a whole number, then 4 and 2,242,516.25 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 | 8,970,065 | |
| -1 | 8,970,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 2,339 | 3,835 | 11,695 | 30,407 | 138,001 | 152,035 | 690,005 | 1,794,013 | 8,970,065 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -2,339 | -3,835 | -11,695 | -30,407 | -138,001 | -152,035 | -690,005 | -1,794,013 | -8,970,065 |
