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 531,024,013, 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 | 531,024,013 | |
| -1 | -531,024,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,024,013.
Example:
1 x 531,024,013 = 531,024,013
and
-1 x -531,024,013 = 531,024,013
Notice both answers equal 531,024,013
With that explanation out of the way, let's continue. Next, we take the number 531,024,013 and divide it by 2:
531,024,013 ÷ 2 = 265,512,006.5
If the quotient is a whole number, then 2 and 265,512,006.5 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 | 531,024,013 | |
| -1 | -531,024,013 |
Now, we try dividing 531,024,013 by 3:
531,024,013 ÷ 3 = 177,008,004.3333
If the quotient is a whole number, then 3 and 177,008,004.3333 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 | 531,024,013 | |
| -1 | -531,024,013 |
Let's try dividing by 4:
531,024,013 ÷ 4 = 132,756,003.25
If the quotient is a whole number, then 4 and 132,756,003.25 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 | 531,024,013 | |
| -1 | 531,024,013 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 59 | 689 | 767 | 3,127 | 13,063 | 40,651 | 169,819 | 692,339 | 770,717 | 9,000,407 | 10,019,321 | 40,848,001 | 531,024,013 |
| -1 | -13 | -53 | -59 | -689 | -767 | -3,127 | -13,063 | -40,651 | -169,819 | -692,339 | -770,717 | -9,000,407 | -10,019,321 | -40,848,001 | -531,024,013 |
