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 531,825,181, 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 | 531,825,181 | |
| -1 | -531,825,181 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,825,181.
Example:
1 x 531,825,181 = 531,825,181
and
-1 x -531,825,181 = 531,825,181
Notice both answers equal 531,825,181
With that explanation out of the way, let's continue. Next, we take the number 531,825,181 and divide it by 2:
531,825,181 ÷ 2 = 265,912,590.5
If the quotient is a whole number, then 2 and 265,912,590.5 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 | 531,825,181 | |
| -1 | -531,825,181 |
Now, we try dividing 531,825,181 by 3:
531,825,181 ÷ 3 = 177,275,060.3333
If the quotient is a whole number, then 3 and 177,275,060.3333 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 | 531,825,181 | |
| -1 | -531,825,181 |
Let's try dividing by 4:
531,825,181 ÷ 4 = 132,956,295.25
If the quotient is a whole number, then 4 and 132,956,295.25 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 | 531,825,181 | |
| -1 | 531,825,181 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 541 | 589 | 1,669 | 10,279 | 16,771 | 31,711 | 51,739 | 318,649 | 902,929 | 983,041 | 17,155,651 | 27,990,799 | 531,825,181 |
| -1 | -19 | -31 | -541 | -589 | -1,669 | -10,279 | -16,771 | -31,711 | -51,739 | -318,649 | -902,929 | -983,041 | -17,155,651 | -27,990,799 | -531,825,181 |
