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 9,194,339, 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 | 9,194,339 | |
| -1 | -9,194,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,194,339.
Example:
1 x 9,194,339 = 9,194,339
and
-1 x -9,194,339 = 9,194,339
Notice both answers equal 9,194,339
With that explanation out of the way, let's continue. Next, we take the number 9,194,339 and divide it by 2:
9,194,339 ÷ 2 = 4,597,169.5
If the quotient is a whole number, then 2 and 4,597,169.5 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 | 9,194,339 | |
| -1 | -9,194,339 |
Now, we try dividing 9,194,339 by 3:
9,194,339 ÷ 3 = 3,064,779.6667
If the quotient is a whole number, then 3 and 3,064,779.6667 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 | 9,194,339 | |
| -1 | -9,194,339 |
Let's try dividing by 4:
9,194,339 ÷ 4 = 2,298,584.75
If the quotient is a whole number, then 4 and 2,298,584.75 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 | 9,194,339 | |
| -1 | 9,194,339 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 97 | 679 | 1,067 | 1,231 | 7,469 | 8,617 | 13,541 | 94,787 | 119,407 | 835,849 | 1,313,477 | 9,194,339 |
| -1 | -7 | -11 | -77 | -97 | -679 | -1,067 | -1,231 | -7,469 | -8,617 | -13,541 | -94,787 | -119,407 | -835,849 | -1,313,477 | -9,194,339 |
