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 8,285,615, 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 | 8,285,615 | |
| -1 | -8,285,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,285,615.
Example:
1 x 8,285,615 = 8,285,615
and
-1 x -8,285,615 = 8,285,615
Notice both answers equal 8,285,615
With that explanation out of the way, let's continue. Next, we take the number 8,285,615 and divide it by 2:
8,285,615 ÷ 2 = 4,142,807.5
If the quotient is a whole number, then 2 and 4,142,807.5 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 | 8,285,615 | |
| -1 | -8,285,615 |
Now, we try dividing 8,285,615 by 3:
8,285,615 ÷ 3 = 2,761,871.6667
If the quotient is a whole number, then 3 and 2,761,871.6667 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 | 8,285,615 | |
| -1 | -8,285,615 |
Let's try dividing by 4:
8,285,615 ÷ 4 = 2,071,403.75
If the quotient is a whole number, then 4 and 2,071,403.75 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 | 8,285,615 | |
| -1 | 8,285,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 6,709 | 33,545 | 87,217 | 127,471 | 436,085 | 637,355 | 1,657,123 | 8,285,615 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -6,709 | -33,545 | -87,217 | -127,471 | -436,085 | -637,355 | -1,657,123 | -8,285,615 |
