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 8,147,711, 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 | 8,147,711 | |
| -1 | -8,147,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,147,711.
Example:
1 x 8,147,711 = 8,147,711
and
-1 x -8,147,711 = 8,147,711
Notice both answers equal 8,147,711
With that explanation out of the way, let's continue. Next, we take the number 8,147,711 and divide it by 2:
8,147,711 ÷ 2 = 4,073,855.5
If the quotient is a whole number, then 2 and 4,073,855.5 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 | 8,147,711 | |
| -1 | -8,147,711 |
Now, we try dividing 8,147,711 by 3:
8,147,711 ÷ 3 = 2,715,903.6667
If the quotient is a whole number, then 3 and 2,715,903.6667 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 | 8,147,711 | |
| -1 | -8,147,711 |
Let's try dividing by 4:
8,147,711 ÷ 4 = 2,036,927.75
If the quotient is a whole number, then 4 and 2,036,927.75 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 | 8,147,711 | |
| -1 | 8,147,711 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 227 | 251 | 2,497 | 2,761 | 2,951 | 3,263 | 32,461 | 35,893 | 56,977 | 626,747 | 740,701 | 8,147,711 |
| -1 | -11 | -13 | -143 | -227 | -251 | -2,497 | -2,761 | -2,951 | -3,263 | -32,461 | -35,893 | -56,977 | -626,747 | -740,701 | -8,147,711 |
