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 9,893,795, 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 | 9,893,795 | |
| -1 | -9,893,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,893,795.
Example:
1 x 9,893,795 = 9,893,795
and
-1 x -9,893,795 = 9,893,795
Notice both answers equal 9,893,795
With that explanation out of the way, let's continue. Next, we take the number 9,893,795 and divide it by 2:
9,893,795 ÷ 2 = 4,946,897.5
If the quotient is a whole number, then 2 and 4,946,897.5 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 | 9,893,795 | |
| -1 | -9,893,795 |
Now, we try dividing 9,893,795 by 3:
9,893,795 ÷ 3 = 3,297,931.6667
If the quotient is a whole number, then 3 and 3,297,931.6667 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 | 9,893,795 | |
| -1 | -9,893,795 |
Let's try dividing by 4:
9,893,795 ÷ 4 = 2,473,448.75
If the quotient is a whole number, then 4 and 2,473,448.75 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 | 9,893,795 | |
| -1 | 9,893,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 227 | 379 | 1,135 | 1,895 | 5,221 | 8,717 | 26,105 | 43,585 | 86,033 | 430,165 | 1,978,759 | 9,893,795 |
| -1 | -5 | -23 | -115 | -227 | -379 | -1,135 | -1,895 | -5,221 | -8,717 | -26,105 | -43,585 | -86,033 | -430,165 | -1,978,759 | -9,893,795 |
