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 525,020,431, 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 | 525,020,431 | |
| -1 | -525,020,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,020,431.
Example:
1 x 525,020,431 = 525,020,431
and
-1 x -525,020,431 = 525,020,431
Notice both answers equal 525,020,431
With that explanation out of the way, let's continue. Next, we take the number 525,020,431 and divide it by 2:
525,020,431 ÷ 2 = 262,510,215.5
If the quotient is a whole number, then 2 and 262,510,215.5 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 | 525,020,431 | |
| -1 | -525,020,431 |
Now, we try dividing 525,020,431 by 3:
525,020,431 ÷ 3 = 175,006,810.3333
If the quotient is a whole number, then 3 and 175,006,810.3333 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 | 525,020,431 | |
| -1 | -525,020,431 |
Let's try dividing by 4:
525,020,431 ÷ 4 = 131,255,107.75
If the quotient is a whole number, then 4 and 131,255,107.75 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 | 525,020,431 | |
| -1 | 525,020,431 |
If you did it right, you will end up with this table:
| 1 | 13 | 107 | 587 | 643 | 1,391 | 7,631 | 8,359 | 62,809 | 68,801 | 377,441 | 816,517 | 894,413 | 4,906,733 | 40,386,187 | 525,020,431 |
| -1 | -13 | -107 | -587 | -643 | -1,391 | -7,631 | -8,359 | -62,809 | -68,801 | -377,441 | -816,517 | -894,413 | -4,906,733 | -40,386,187 | -525,020,431 |
