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 236,162,245, 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 | 236,162,245 | |
| -1 | -236,162,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 236,162,245.
Example:
1 x 236,162,245 = 236,162,245
and
-1 x -236,162,245 = 236,162,245
Notice both answers equal 236,162,245
With that explanation out of the way, let's continue. Next, we take the number 236,162,245 and divide it by 2:
236,162,245 ÷ 2 = 118,081,122.5
If the quotient is a whole number, then 2 and 118,081,122.5 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 | 236,162,245 | |
| -1 | -236,162,245 |
Now, we try dividing 236,162,245 by 3:
236,162,245 ÷ 3 = 78,720,748.3333
If the quotient is a whole number, then 3 and 78,720,748.3333 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 | 236,162,245 | |
| -1 | -236,162,245 |
Let's try dividing by 4:
236,162,245 ÷ 4 = 59,040,561.25
If the quotient is a whole number, then 4 and 59,040,561.25 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 | 236,162,245 | |
| -1 | 236,162,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 439 | 2,195 | 4,829 | 9,781 | 24,145 | 48,905 | 107,591 | 537,955 | 4,293,859 | 21,469,295 | 47,232,449 | 236,162,245 |
| -1 | -5 | -11 | -55 | -439 | -2,195 | -4,829 | -9,781 | -24,145 | -48,905 | -107,591 | -537,955 | -4,293,859 | -21,469,295 | -47,232,449 | -236,162,245 |
