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 523,124,315, 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 | 523,124,315 | |
| -1 | -523,124,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 523,124,315.
Example:
1 x 523,124,315 = 523,124,315
and
-1 x -523,124,315 = 523,124,315
Notice both answers equal 523,124,315
With that explanation out of the way, let's continue. Next, we take the number 523,124,315 and divide it by 2:
523,124,315 ÷ 2 = 261,562,157.5
If the quotient is a whole number, then 2 and 261,562,157.5 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 | 523,124,315 | |
| -1 | -523,124,315 |
Now, we try dividing 523,124,315 by 3:
523,124,315 ÷ 3 = 174,374,771.6667
If the quotient is a whole number, then 3 and 174,374,771.6667 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 | 523,124,315 | |
| -1 | -523,124,315 |
Let's try dividing by 4:
523,124,315 ÷ 4 = 130,781,078.75
If the quotient is a whole number, then 4 and 130,781,078.75 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 | 523,124,315 | |
| -1 | 523,124,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 1,295 | 403,957 | 2,019,785 | 2,827,699 | 14,138,495 | 14,946,409 | 74,732,045 | 104,624,863 | 523,124,315 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -1,295 | -403,957 | -2,019,785 | -2,827,699 | -14,138,495 | -14,946,409 | -74,732,045 | -104,624,863 | -523,124,315 |
