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 238,767,683, 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 | 238,767,683 | |
| -1 | -238,767,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 238,767,683.
Example:
1 x 238,767,683 = 238,767,683
and
-1 x -238,767,683 = 238,767,683
Notice both answers equal 238,767,683
With that explanation out of the way, let's continue. Next, we take the number 238,767,683 and divide it by 2:
238,767,683 ÷ 2 = 119,383,841.5
If the quotient is a whole number, then 2 and 119,383,841.5 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 | 238,767,683 | |
| -1 | -238,767,683 |
Now, we try dividing 238,767,683 by 3:
238,767,683 ÷ 3 = 79,589,227.6667
If the quotient is a whole number, then 3 and 79,589,227.6667 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 | 238,767,683 | |
| -1 | -238,767,683 |
Let's try dividing by 4:
238,767,683 ÷ 4 = 59,691,920.75
If the quotient is a whole number, then 4 and 59,691,920.75 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 | 238,767,683 | |
| -1 | 238,767,683 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 751 | 4,129 | 5,257 | 8,261 | 28,903 | 45,419 | 57,827 | 317,933 | 3,100,879 | 21,706,153 | 34,109,669 | 238,767,683 |
| -1 | -7 | -11 | -77 | -751 | -4,129 | -5,257 | -8,261 | -28,903 | -45,419 | -57,827 | -317,933 | -3,100,879 | -21,706,153 | -34,109,669 | -238,767,683 |
