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 113,535,521, 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 | 113,535,521 | |
| -1 | -113,535,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,535,521.
Example:
1 x 113,535,521 = 113,535,521
and
-1 x -113,535,521 = 113,535,521
Notice both answers equal 113,535,521
With that explanation out of the way, let's continue. Next, we take the number 113,535,521 and divide it by 2:
113,535,521 ÷ 2 = 56,767,760.5
If the quotient is a whole number, then 2 and 56,767,760.5 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 | 113,535,521 | |
| -1 | -113,535,521 |
Now, we try dividing 113,535,521 by 3:
113,535,521 ÷ 3 = 37,845,173.6667
If the quotient is a whole number, then 3 and 37,845,173.6667 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 | 113,535,521 | |
| -1 | -113,535,521 |
Let's try dividing by 4:
113,535,521 ÷ 4 = 28,383,880.25
If the quotient is a whole number, then 4 and 28,383,880.25 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 | 113,535,521 | |
| -1 | 113,535,521 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 281 | 1,597 | 3,091 | 6,463 | 17,567 | 36,731 | 71,093 | 404,041 | 448,757 | 4,936,327 | 10,321,411 | 113,535,521 |
| -1 | -11 | -23 | -253 | -281 | -1,597 | -3,091 | -6,463 | -17,567 | -36,731 | -71,093 | -404,041 | -448,757 | -4,936,327 | -10,321,411 | -113,535,521 |
