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 523,355,437, 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 | 523,355,437 | |
| -1 | -523,355,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 523,355,437.
Example:
1 x 523,355,437 = 523,355,437
and
-1 x -523,355,437 = 523,355,437
Notice both answers equal 523,355,437
With that explanation out of the way, let's continue. Next, we take the number 523,355,437 and divide it by 2:
523,355,437 ÷ 2 = 261,677,718.5
If the quotient is a whole number, then 2 and 261,677,718.5 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 | 523,355,437 | |
| -1 | -523,355,437 |
Now, we try dividing 523,355,437 by 3:
523,355,437 ÷ 3 = 174,451,812.3333
If the quotient is a whole number, then 3 and 174,451,812.3333 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 | 523,355,437 | |
| -1 | -523,355,437 |
Let's try dividing by 4:
523,355,437 ÷ 4 = 130,838,859.25
If the quotient is a whole number, then 4 and 130,838,859.25 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 | 523,355,437 | |
| -1 | 523,355,437 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 101 | 209 | 1,111 | 1,919 | 21,109 | 24,793 | 272,723 | 471,067 | 2,504,093 | 5,181,737 | 27,545,023 | 47,577,767 | 523,355,437 |
| -1 | -11 | -19 | -101 | -209 | -1,111 | -1,919 | -21,109 | -24,793 | -272,723 | -471,067 | -2,504,093 | -5,181,737 | -27,545,023 | -47,577,767 | -523,355,437 |
