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 525,403,403, 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 | 525,403,403 | |
| -1 | -525,403,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,403,403.
Example:
1 x 525,403,403 = 525,403,403
and
-1 x -525,403,403 = 525,403,403
Notice both answers equal 525,403,403
With that explanation out of the way, let's continue. Next, we take the number 525,403,403 and divide it by 2:
525,403,403 ÷ 2 = 262,701,701.5
If the quotient is a whole number, then 2 and 262,701,701.5 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 | 525,403,403 | |
| -1 | -525,403,403 |
Now, we try dividing 525,403,403 by 3:
525,403,403 ÷ 3 = 175,134,467.6667
If the quotient is a whole number, then 3 and 175,134,467.6667 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 | 525,403,403 | |
| -1 | -525,403,403 |
Let's try dividing by 4:
525,403,403 ÷ 4 = 131,350,850.75
If the quotient is a whole number, then 4 and 131,350,850.75 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 | 525,403,403 | |
| -1 | 525,403,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 131 | 281 | 917 | 1,967 | 2,039 | 14,273 | 36,811 | 257,677 | 267,109 | 572,959 | 1,869,763 | 4,010,713 | 75,057,629 | 525,403,403 |
| -1 | -7 | -131 | -281 | -917 | -1,967 | -2,039 | -14,273 | -36,811 | -257,677 | -267,109 | -572,959 | -1,869,763 | -4,010,713 | -75,057,629 | -525,403,403 |
