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 525,615,101, 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 | 525,615,101 | |
| -1 | -525,615,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,615,101.
Example:
1 x 525,615,101 = 525,615,101
and
-1 x -525,615,101 = 525,615,101
Notice both answers equal 525,615,101
With that explanation out of the way, let's continue. Next, we take the number 525,615,101 and divide it by 2:
525,615,101 ÷ 2 = 262,807,550.5
If the quotient is a whole number, then 2 and 262,807,550.5 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 | 525,615,101 | |
| -1 | -525,615,101 |
Now, we try dividing 525,615,101 by 3:
525,615,101 ÷ 3 = 175,205,033.6667
If the quotient is a whole number, then 3 and 175,205,033.6667 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 | 525,615,101 | |
| -1 | -525,615,101 |
Let's try dividing by 4:
525,615,101 ÷ 4 = 131,403,775.25
If the quotient is a whole number, then 4 and 131,403,775.25 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 | 525,615,101 | |
| -1 | 525,615,101 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 61 | 473 | 671 | 2,623 | 18,217 | 28,853 | 200,387 | 783,331 | 1,111,237 | 8,616,641 | 12,223,607 | 47,783,191 | 525,615,101 |
| -1 | -11 | -43 | -61 | -473 | -671 | -2,623 | -18,217 | -28,853 | -200,387 | -783,331 | -1,111,237 | -8,616,641 | -12,223,607 | -47,783,191 | -525,615,101 |
