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 238,775,335, 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 | 238,775,335 | |
| -1 | -238,775,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 238,775,335.
Example:
1 x 238,775,335 = 238,775,335
and
-1 x -238,775,335 = 238,775,335
Notice both answers equal 238,775,335
With that explanation out of the way, let's continue. Next, we take the number 238,775,335 and divide it by 2:
238,775,335 ÷ 2 = 119,387,667.5
If the quotient is a whole number, then 2 and 119,387,667.5 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 | 238,775,335 | |
| -1 | -238,775,335 |
Now, we try dividing 238,775,335 by 3:
238,775,335 ÷ 3 = 79,591,778.3333
If the quotient is a whole number, then 3 and 79,591,778.3333 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 | 238,775,335 | |
| -1 | -238,775,335 |
Let's try dividing by 4:
238,775,335 ÷ 4 = 59,693,833.75
If the quotient is a whole number, then 4 and 59,693,833.75 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 | 238,775,335 | |
| -1 | 238,775,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 73 | 265 | 365 | 3,869 | 12,343 | 19,345 | 61,715 | 654,179 | 901,039 | 3,270,895 | 4,505,195 | 47,755,067 | 238,775,335 |
| -1 | -5 | -53 | -73 | -265 | -365 | -3,869 | -12,343 | -19,345 | -61,715 | -654,179 | -901,039 | -3,270,895 | -4,505,195 | -47,755,067 | -238,775,335 |
