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 233,443,423, 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 | 233,443,423 | |
| -1 | -233,443,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,443,423.
Example:
1 x 233,443,423 = 233,443,423
and
-1 x -233,443,423 = 233,443,423
Notice both answers equal 233,443,423
With that explanation out of the way, let's continue. Next, we take the number 233,443,423 and divide it by 2:
233,443,423 ÷ 2 = 116,721,711.5
If the quotient is a whole number, then 2 and 116,721,711.5 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 | 233,443,423 | |
| -1 | -233,443,423 |
Now, we try dividing 233,443,423 by 3:
233,443,423 ÷ 3 = 77,814,474.3333
If the quotient is a whole number, then 3 and 77,814,474.3333 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 | 233,443,423 | |
| -1 | -233,443,423 |
Let's try dividing by 4:
233,443,423 ÷ 4 = 58,360,855.75
If the quotient is a whole number, then 4 and 58,360,855.75 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 | 233,443,423 | |
| -1 | 233,443,423 |
If you did it right, you will end up with this table:
| 1 | 31 | 103 | 113 | 647 | 3,193 | 3,503 | 11,639 | 20,057 | 66,641 | 73,111 | 360,809 | 2,065,871 | 2,266,441 | 7,530,433 | 233,443,423 |
| -1 | -31 | -103 | -113 | -647 | -3,193 | -3,503 | -11,639 | -20,057 | -66,641 | -73,111 | -360,809 | -2,065,871 | -2,266,441 | -7,530,433 | -233,443,423 |
