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 525,316,231, 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 | 525,316,231 | |
| -1 | -525,316,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,316,231.
Example:
1 x 525,316,231 = 525,316,231
and
-1 x -525,316,231 = 525,316,231
Notice both answers equal 525,316,231
With that explanation out of the way, let's continue. Next, we take the number 525,316,231 and divide it by 2:
525,316,231 ÷ 2 = 262,658,115.5
If the quotient is a whole number, then 2 and 262,658,115.5 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 | 525,316,231 | |
| -1 | -525,316,231 |
Now, we try dividing 525,316,231 by 3:
525,316,231 ÷ 3 = 175,105,410.3333
If the quotient is a whole number, then 3 and 175,105,410.3333 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 | 525,316,231 | |
| -1 | -525,316,231 |
Let's try dividing by 4:
525,316,231 ÷ 4 = 131,329,057.75
If the quotient is a whole number, then 4 and 131,329,057.75 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 | 525,316,231 | |
| -1 | 525,316,231 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 53 | 451 | 583 | 2,173 | 21,977 | 23,903 | 241,747 | 901,057 | 1,164,781 | 9,911,627 | 12,812,591 | 47,756,021 | 525,316,231 |
| -1 | -11 | -41 | -53 | -451 | -583 | -2,173 | -21,977 | -23,903 | -241,747 | -901,057 | -1,164,781 | -9,911,627 | -12,812,591 | -47,756,021 | -525,316,231 |
