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 9,177,509, 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 | 9,177,509 | |
| -1 | -9,177,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,177,509.
Example:
1 x 9,177,509 = 9,177,509
and
-1 x -9,177,509 = 9,177,509
Notice both answers equal 9,177,509
With that explanation out of the way, let's continue. Next, we take the number 9,177,509 and divide it by 2:
9,177,509 ÷ 2 = 4,588,754.5
If the quotient is a whole number, then 2 and 4,588,754.5 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 | 9,177,509 | |
| -1 | -9,177,509 |
Now, we try dividing 9,177,509 by 3:
9,177,509 ÷ 3 = 3,059,169.6667
If the quotient is a whole number, then 3 and 3,059,169.6667 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 | 9,177,509 | |
| -1 | -9,177,509 |
Let's try dividing by 4:
9,177,509 ÷ 4 = 2,294,377.25
If the quotient is a whole number, then 4 and 2,294,377.25 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 | 9,177,509 | |
| -1 | 9,177,509 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 79 | 179 | 649 | 869 | 1,969 | 4,661 | 10,561 | 14,141 | 51,271 | 116,171 | 155,551 | 834,319 | 9,177,509 |
| -1 | -11 | -59 | -79 | -179 | -649 | -869 | -1,969 | -4,661 | -10,561 | -14,141 | -51,271 | -116,171 | -155,551 | -834,319 | -9,177,509 |
