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 523,355,443, 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 | 523,355,443 | |
| -1 | -523,355,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 523,355,443.
Example:
1 x 523,355,443 = 523,355,443
and
-1 x -523,355,443 = 523,355,443
Notice both answers equal 523,355,443
With that explanation out of the way, let's continue. Next, we take the number 523,355,443 and divide it by 2:
523,355,443 ÷ 2 = 261,677,721.5
If the quotient is a whole number, then 2 and 261,677,721.5 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 | 523,355,443 | |
| -1 | -523,355,443 |
Now, we try dividing 523,355,443 by 3:
523,355,443 ÷ 3 = 174,451,814.3333
If the quotient is a whole number, then 3 and 174,451,814.3333 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 | 523,355,443 | |
| -1 | -523,355,443 |
Let's try dividing by 4:
523,355,443 ÷ 4 = 130,838,860.75
If the quotient is a whole number, then 4 and 130,838,860.75 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 | 523,355,443 | |
| -1 | 523,355,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 127 | 689 | 1,651 | 5,981 | 6,731 | 77,753 | 87,503 | 316,993 | 759,587 | 4,120,909 | 9,874,631 | 40,258,111 | 523,355,443 |
| -1 | -13 | -53 | -127 | -689 | -1,651 | -5,981 | -6,731 | -77,753 | -87,503 | -316,993 | -759,587 | -4,120,909 | -9,874,631 | -40,258,111 | -523,355,443 |
