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 523,400,015, 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 | 523,400,015 | |
| -1 | -523,400,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 523,400,015.
Example:
1 x 523,400,015 = 523,400,015
and
-1 x -523,400,015 = 523,400,015
Notice both answers equal 523,400,015
With that explanation out of the way, let's continue. Next, we take the number 523,400,015 and divide it by 2:
523,400,015 ÷ 2 = 261,700,007.5
If the quotient is a whole number, then 2 and 261,700,007.5 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 | 523,400,015 | |
| -1 | -523,400,015 |
Now, we try dividing 523,400,015 by 3:
523,400,015 ÷ 3 = 174,466,671.6667
If the quotient is a whole number, then 3 and 174,466,671.6667 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 | 523,400,015 | |
| -1 | -523,400,015 |
Let's try dividing by 4:
523,400,015 ÷ 4 = 130,850,003.75
If the quotient is a whole number, then 4 and 130,850,003.75 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 | 523,400,015 | |
| -1 | 523,400,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 545 | 727 | 1,321 | 3,635 | 6,605 | 79,243 | 143,989 | 396,215 | 719,945 | 960,367 | 4,801,835 | 104,680,003 | 523,400,015 |
| -1 | -5 | -109 | -545 | -727 | -1,321 | -3,635 | -6,605 | -79,243 | -143,989 | -396,215 | -719,945 | -960,367 | -4,801,835 | -104,680,003 | -523,400,015 |
