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 2,504,015, 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 | 2,504,015 | |
| -1 | -2,504,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,504,015.
Example:
1 x 2,504,015 = 2,504,015
and
-1 x -2,504,015 = 2,504,015
Notice both answers equal 2,504,015
With that explanation out of the way, let's continue. Next, we take the number 2,504,015 and divide it by 2:
2,504,015 ÷ 2 = 1,252,007.5
If the quotient is a whole number, then 2 and 1,252,007.5 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 | 2,504,015 | |
| -1 | -2,504,015 |
Now, we try dividing 2,504,015 by 3:
2,504,015 ÷ 3 = 834,671.6667
If the quotient is a whole number, then 3 and 834,671.6667 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 | 2,504,015 | |
| -1 | -2,504,015 |
Let's try dividing by 4:
2,504,015 ÷ 4 = 626,003.75
If the quotient is a whole number, then 4 and 626,003.75 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 | 2,504,015 | |
| -1 | 2,504,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 89 | 331 | 445 | 1,513 | 1,655 | 5,627 | 7,565 | 28,135 | 29,459 | 147,295 | 500,803 | 2,504,015 |
| -1 | -5 | -17 | -85 | -89 | -331 | -445 | -1,513 | -1,655 | -5,627 | -7,565 | -28,135 | -29,459 | -147,295 | -500,803 | -2,504,015 |
