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 8,782,505, 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 | 8,782,505 | |
| -1 | -8,782,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,782,505.
Example:
1 x 8,782,505 = 8,782,505
and
-1 x -8,782,505 = 8,782,505
Notice both answers equal 8,782,505
With that explanation out of the way, let's continue. Next, we take the number 8,782,505 and divide it by 2:
8,782,505 ÷ 2 = 4,391,252.5
If the quotient is a whole number, then 2 and 4,391,252.5 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 | 8,782,505 | |
| -1 | -8,782,505 |
Now, we try dividing 8,782,505 by 3:
8,782,505 ÷ 3 = 2,927,501.6667
If the quotient is a whole number, then 3 and 2,927,501.6667 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 | 8,782,505 | |
| -1 | -8,782,505 |
Let's try dividing by 4:
8,782,505 ÷ 4 = 2,195,626.25
If the quotient is a whole number, then 4 and 2,195,626.25 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 | 8,782,505 | |
| -1 | 8,782,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 1,073 | 1,637 | 5,365 | 8,185 | 47,473 | 60,569 | 237,365 | 302,845 | 1,756,501 | 8,782,505 |
| -1 | -5 | -29 | -37 | -145 | -185 | -1,073 | -1,637 | -5,365 | -8,185 | -47,473 | -60,569 | -237,365 | -302,845 | -1,756,501 | -8,782,505 |
