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 8,716,169, 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 | 8,716,169 | |
| -1 | -8,716,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,716,169.
Example:
1 x 8,716,169 = 8,716,169
and
-1 x -8,716,169 = 8,716,169
Notice both answers equal 8,716,169
With that explanation out of the way, let's continue. Next, we take the number 8,716,169 and divide it by 2:
8,716,169 ÷ 2 = 4,358,084.5
If the quotient is a whole number, then 2 and 4,358,084.5 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 | 8,716,169 | |
| -1 | -8,716,169 |
Now, we try dividing 8,716,169 by 3:
8,716,169 ÷ 3 = 2,905,389.6667
If the quotient is a whole number, then 3 and 2,905,389.6667 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 | 8,716,169 | |
| -1 | -8,716,169 |
Let's try dividing by 4:
8,716,169 ÷ 4 = 2,179,042.25
If the quotient is a whole number, then 4 and 2,179,042.25 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 | 8,716,169 | |
| -1 | 8,716,169 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 103 | 157 | 539 | 721 | 1,099 | 1,133 | 1,727 | 5,047 | 7,693 | 7,931 | 12,089 | 16,171 | 55,517 | 84,623 | 113,197 | 177,881 | 792,379 | 1,245,167 | 8,716,169 |
| -1 | -7 | -11 | -49 | -77 | -103 | -157 | -539 | -721 | -1,099 | -1,133 | -1,727 | -5,047 | -7,693 | -7,931 | -12,089 | -16,171 | -55,517 | -84,623 | -113,197 | -177,881 | -792,379 | -1,245,167 | -8,716,169 |
