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 8,796,487, 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 | 8,796,487 | |
| -1 | -8,796,487 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,796,487.
Example:
1 x 8,796,487 = 8,796,487
and
-1 x -8,796,487 = 8,796,487
Notice both answers equal 8,796,487
With that explanation out of the way, let's continue. Next, we take the number 8,796,487 and divide it by 2:
8,796,487 ÷ 2 = 4,398,243.5
If the quotient is a whole number, then 2 and 4,398,243.5 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 | 8,796,487 | |
| -1 | -8,796,487 |
Now, we try dividing 8,796,487 by 3:
8,796,487 ÷ 3 = 2,932,162.3333
If the quotient is a whole number, then 3 and 2,932,162.3333 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 | 8,796,487 | |
| -1 | -8,796,487 |
Let's try dividing by 4:
8,796,487 ÷ 4 = 2,199,121.75
If the quotient is a whole number, then 4 and 2,199,121.75 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 | 8,796,487 | |
| -1 | 8,796,487 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 361 | 413 | 1,121 | 2,527 | 3,481 | 7,847 | 21,299 | 24,367 | 66,139 | 149,093 | 462,973 | 1,256,641 | 8,796,487 |
| -1 | -7 | -19 | -59 | -133 | -361 | -413 | -1,121 | -2,527 | -3,481 | -7,847 | -21,299 | -24,367 | -66,139 | -149,093 | -462,973 | -1,256,641 | -8,796,487 |
