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 532,664,075, 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 | 532,664,075 | |
| -1 | -532,664,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 532,664,075.
Example:
1 x 532,664,075 = 532,664,075
and
-1 x -532,664,075 = 532,664,075
Notice both answers equal 532,664,075
With that explanation out of the way, let's continue. Next, we take the number 532,664,075 and divide it by 2:
532,664,075 ÷ 2 = 266,332,037.5
If the quotient is a whole number, then 2 and 266,332,037.5 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 | 532,664,075 | |
| -1 | -532,664,075 |
Now, we try dividing 532,664,075 by 3:
532,664,075 ÷ 3 = 177,554,691.6667
If the quotient is a whole number, then 3 and 177,554,691.6667 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 | 532,664,075 | |
| -1 | -532,664,075 |
Let's try dividing by 4:
532,664,075 ÷ 4 = 133,166,018.75
If the quotient is a whole number, then 4 and 133,166,018.75 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 | 532,664,075 | |
| -1 | 532,664,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 277 | 1,385 | 6,925 | 76,919 | 384,595 | 1,922,975 | 21,306,563 | 106,532,815 | 532,664,075 |
| -1 | -5 | -25 | -277 | -1,385 | -6,925 | -76,919 | -384,595 | -1,922,975 | -21,306,563 | -106,532,815 | -532,664,075 |
