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 8,014,787, 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 | 8,014,787 | |
| -1 | -8,014,787 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,014,787.
Example:
1 x 8,014,787 = 8,014,787
and
-1 x -8,014,787 = 8,014,787
Notice both answers equal 8,014,787
With that explanation out of the way, let's continue. Next, we take the number 8,014,787 and divide it by 2:
8,014,787 ÷ 2 = 4,007,393.5
If the quotient is a whole number, then 2 and 4,007,393.5 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 | 8,014,787 | |
| -1 | -8,014,787 |
Now, we try dividing 8,014,787 by 3:
8,014,787 ÷ 3 = 2,671,595.6667
If the quotient is a whole number, then 3 and 2,671,595.6667 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 | 8,014,787 | |
| -1 | -8,014,787 |
Let's try dividing by 4:
8,014,787 ÷ 4 = 2,003,696.75
If the quotient is a whole number, then 4 and 2,003,696.75 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 | 8,014,787 | |
| -1 | 8,014,787 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 79 | 253 | 401 | 869 | 1,817 | 4,411 | 9,223 | 19,987 | 31,679 | 101,453 | 348,469 | 728,617 | 8,014,787 |
| -1 | -11 | -23 | -79 | -253 | -401 | -869 | -1,817 | -4,411 | -9,223 | -19,987 | -31,679 | -101,453 | -348,469 | -728,617 | -8,014,787 |
