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 504,443,521, 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 | 504,443,521 | |
| -1 | -504,443,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 504,443,521.
Example:
1 x 504,443,521 = 504,443,521
and
-1 x -504,443,521 = 504,443,521
Notice both answers equal 504,443,521
With that explanation out of the way, let's continue. Next, we take the number 504,443,521 and divide it by 2:
504,443,521 ÷ 2 = 252,221,760.5
If the quotient is a whole number, then 2 and 252,221,760.5 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 | 504,443,521 | |
| -1 | -504,443,521 |
Now, we try dividing 504,443,521 by 3:
504,443,521 ÷ 3 = 168,147,840.3333
If the quotient is a whole number, then 3 and 168,147,840.3333 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 | 504,443,521 | |
| -1 | -504,443,521 |
Let's try dividing by 4:
504,443,521 ÷ 4 = 126,110,880.25
If the quotient is a whole number, then 4 and 126,110,880.25 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 | 504,443,521 | |
| -1 | 504,443,521 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 193 | 437 | 3,667 | 4,439 | 5,981 | 84,341 | 113,639 | 137,563 | 1,154,333 | 2,613,697 | 21,932,327 | 26,549,659 | 504,443,521 |
| -1 | -19 | -23 | -193 | -437 | -3,667 | -4,439 | -5,981 | -84,341 | -113,639 | -137,563 | -1,154,333 | -2,613,697 | -21,932,327 | -26,549,659 | -504,443,521 |
