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 2,535,499, 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 | 2,535,499 | |
| -1 | -2,535,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,535,499.
Example:
1 x 2,535,499 = 2,535,499
and
-1 x -2,535,499 = 2,535,499
Notice both answers equal 2,535,499
With that explanation out of the way, let's continue. Next, we take the number 2,535,499 and divide it by 2:
2,535,499 ÷ 2 = 1,267,749.5
If the quotient is a whole number, then 2 and 1,267,749.5 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 | 2,535,499 | |
| -1 | -2,535,499 |
Now, we try dividing 2,535,499 by 3:
2,535,499 ÷ 3 = 845,166.3333
If the quotient is a whole number, then 3 and 845,166.3333 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 | 2,535,499 | |
| -1 | -2,535,499 |
Let's try dividing by 4:
2,535,499 ÷ 4 = 633,874.75
If the quotient is a whole number, then 4 and 633,874.75 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 | 2,535,499 | |
| -1 | 2,535,499 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 37 | 139 | 493 | 629 | 1,073 | 2,363 | 4,031 | 5,143 | 18,241 | 68,527 | 87,431 | 149,147 | 2,535,499 |
| -1 | -17 | -29 | -37 | -139 | -493 | -629 | -1,073 | -2,363 | -4,031 | -5,143 | -18,241 | -68,527 | -87,431 | -149,147 | -2,535,499 |
