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 8,503,675, 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 | 8,503,675 | |
| -1 | -8,503,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,503,675.
Example:
1 x 8,503,675 = 8,503,675
and
-1 x -8,503,675 = 8,503,675
Notice both answers equal 8,503,675
With that explanation out of the way, let's continue. Next, we take the number 8,503,675 and divide it by 2:
8,503,675 ÷ 2 = 4,251,837.5
If the quotient is a whole number, then 2 and 4,251,837.5 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 | 8,503,675 | |
| -1 | -8,503,675 |
Now, we try dividing 8,503,675 by 3:
8,503,675 ÷ 3 = 2,834,558.3333
If the quotient is a whole number, then 3 and 2,834,558.3333 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 | 8,503,675 | |
| -1 | -8,503,675 |
Let's try dividing by 4:
8,503,675 ÷ 4 = 2,125,918.75
If the quotient is a whole number, then 4 and 2,125,918.75 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 | 8,503,675 | |
| -1 | 8,503,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 529 | 575 | 643 | 2,645 | 3,215 | 13,225 | 14,789 | 16,075 | 73,945 | 340,147 | 369,725 | 1,700,735 | 8,503,675 |
| -1 | -5 | -23 | -25 | -115 | -529 | -575 | -643 | -2,645 | -3,215 | -13,225 | -14,789 | -16,075 | -73,945 | -340,147 | -369,725 | -1,700,735 | -8,503,675 |
