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 521,525,075, 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 | 521,525,075 | |
| -1 | -521,525,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 521,525,075.
Example:
1 x 521,525,075 = 521,525,075
and
-1 x -521,525,075 = 521,525,075
Notice both answers equal 521,525,075
With that explanation out of the way, let's continue. Next, we take the number 521,525,075 and divide it by 2:
521,525,075 ÷ 2 = 260,762,537.5
If the quotient is a whole number, then 2 and 260,762,537.5 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 | 521,525,075 | |
| -1 | -521,525,075 |
Now, we try dividing 521,525,075 by 3:
521,525,075 ÷ 3 = 173,841,691.6667
If the quotient is a whole number, then 3 and 173,841,691.6667 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 | 521,525,075 | |
| -1 | -521,525,075 |
Let's try dividing by 4:
521,525,075 ÷ 4 = 130,381,268.75
If the quotient is a whole number, then 4 and 130,381,268.75 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 | 521,525,075 | |
| -1 | 521,525,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 613 | 3,065 | 15,325 | 34,031 | 170,155 | 850,775 | 20,861,003 | 104,305,015 | 521,525,075 |
| -1 | -5 | -25 | -613 | -3,065 | -15,325 | -34,031 | -170,155 | -850,775 | -20,861,003 | -104,305,015 | -521,525,075 |
