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 8,503,285, 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 | 8,503,285 | |
| -1 | -8,503,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,503,285.
Example:
1 x 8,503,285 = 8,503,285
and
-1 x -8,503,285 = 8,503,285
Notice both answers equal 8,503,285
With that explanation out of the way, let's continue. Next, we take the number 8,503,285 and divide it by 2:
8,503,285 ÷ 2 = 4,251,642.5
If the quotient is a whole number, then 2 and 4,251,642.5 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 | 8,503,285 | |
| -1 | -8,503,285 |
Now, we try dividing 8,503,285 by 3:
8,503,285 ÷ 3 = 2,834,428.3333
If the quotient is a whole number, then 3 and 2,834,428.3333 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 | 8,503,285 | |
| -1 | -8,503,285 |
Let's try dividing by 4:
8,503,285 ÷ 4 = 2,125,821.25
If the quotient is a whole number, then 4 and 2,125,821.25 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 | 8,503,285 | |
| -1 | 8,503,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 127 | 635 | 889 | 1,913 | 4,445 | 9,565 | 13,391 | 66,955 | 242,951 | 1,214,755 | 1,700,657 | 8,503,285 |
| -1 | -5 | -7 | -35 | -127 | -635 | -889 | -1,913 | -4,445 | -9,565 | -13,391 | -66,955 | -242,951 | -1,214,755 | -1,700,657 | -8,503,285 |
