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 525,424,613, 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 | 525,424,613 | |
| -1 | -525,424,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,424,613.
Example:
1 x 525,424,613 = 525,424,613
and
-1 x -525,424,613 = 525,424,613
Notice both answers equal 525,424,613
With that explanation out of the way, let's continue. Next, we take the number 525,424,613 and divide it by 2:
525,424,613 ÷ 2 = 262,712,306.5
If the quotient is a whole number, then 2 and 262,712,306.5 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 | 525,424,613 | |
| -1 | -525,424,613 |
Now, we try dividing 525,424,613 by 3:
525,424,613 ÷ 3 = 175,141,537.6667
If the quotient is a whole number, then 3 and 175,141,537.6667 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 | 525,424,613 | |
| -1 | -525,424,613 |
Let's try dividing by 4:
525,424,613 ÷ 4 = 131,356,153.25
If the quotient is a whole number, then 4 and 131,356,153.25 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 | 525,424,613 | |
| -1 | 525,424,613 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 439 | 3,073 | 8,341 | 8,999 | 58,387 | 62,993 | 170,981 | 1,196,867 | 3,950,561 | 27,653,927 | 75,060,659 | 525,424,613 |
| -1 | -7 | -19 | -133 | -439 | -3,073 | -8,341 | -8,999 | -58,387 | -62,993 | -170,981 | -1,196,867 | -3,950,561 | -27,653,927 | -75,060,659 | -525,424,613 |
