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 235,536,613, 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 | 235,536,613 | |
| -1 | -235,536,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,536,613.
Example:
1 x 235,536,613 = 235,536,613
and
-1 x -235,536,613 = 235,536,613
Notice both answers equal 235,536,613
With that explanation out of the way, let's continue. Next, we take the number 235,536,613 and divide it by 2:
235,536,613 ÷ 2 = 117,768,306.5
If the quotient is a whole number, then 2 and 117,768,306.5 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 | 235,536,613 | |
| -1 | -235,536,613 |
Now, we try dividing 235,536,613 by 3:
235,536,613 ÷ 3 = 78,512,204.3333
If the quotient is a whole number, then 3 and 78,512,204.3333 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 | 235,536,613 | |
| -1 | -235,536,613 |
Let's try dividing by 4:
235,536,613 ÷ 4 = 58,884,153.25
If the quotient is a whole number, then 4 and 58,884,153.25 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 | 235,536,613 | |
| -1 | 235,536,613 |
If you did it right, you will end up with this table:
| 1 | 13 | 127 | 179 | 797 | 1,651 | 2,327 | 10,361 | 22,733 | 101,219 | 142,663 | 295,529 | 1,315,847 | 1,854,619 | 18,118,201 | 235,536,613 |
| -1 | -13 | -127 | -179 | -797 | -1,651 | -2,327 | -10,361 | -22,733 | -101,219 | -142,663 | -295,529 | -1,315,847 | -1,854,619 | -18,118,201 | -235,536,613 |
