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 238,523,593, 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 | 238,523,593 | |
| -1 | -238,523,593 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 238,523,593.
Example:
1 x 238,523,593 = 238,523,593
and
-1 x -238,523,593 = 238,523,593
Notice both answers equal 238,523,593
With that explanation out of the way, let's continue. Next, we take the number 238,523,593 and divide it by 2:
238,523,593 ÷ 2 = 119,261,796.5
If the quotient is a whole number, then 2 and 119,261,796.5 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 | 238,523,593 | |
| -1 | -238,523,593 |
Now, we try dividing 238,523,593 by 3:
238,523,593 ÷ 3 = 79,507,864.3333
If the quotient is a whole number, then 3 and 79,507,864.3333 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 | 238,523,593 | |
| -1 | -238,523,593 |
Let's try dividing by 4:
238,523,593 ÷ 4 = 59,630,898.25
If the quotient is a whole number, then 4 and 59,630,898.25 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 | 238,523,593 | |
| -1 | 238,523,593 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 134,683 | 942,781 | 1,481,513 | 3,097,709 | 10,370,591 | 21,683,963 | 34,074,799 | 238,523,593 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -134,683 | -942,781 | -1,481,513 | -3,097,709 | -10,370,591 | -21,683,963 | -34,074,799 | -238,523,593 |
