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 236,410,123, 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 | 236,410,123 | |
| -1 | -236,410,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 236,410,123.
Example:
1 x 236,410,123 = 236,410,123
and
-1 x -236,410,123 = 236,410,123
Notice both answers equal 236,410,123
With that explanation out of the way, let's continue. Next, we take the number 236,410,123 and divide it by 2:
236,410,123 ÷ 2 = 118,205,061.5
If the quotient is a whole number, then 2 and 118,205,061.5 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 | 236,410,123 | |
| -1 | -236,410,123 |
Now, we try dividing 236,410,123 by 3:
236,410,123 ÷ 3 = 78,803,374.3333
If the quotient is a whole number, then 3 and 78,803,374.3333 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 | 236,410,123 | |
| -1 | -236,410,123 |
Let's try dividing by 4:
236,410,123 ÷ 4 = 59,102,530.75
If the quotient is a whole number, then 4 and 59,102,530.75 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 | 236,410,123 | |
| -1 | 236,410,123 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 251 | 713 | 1,321 | 5,773 | 7,781 | 30,383 | 40,951 | 178,963 | 331,571 | 941,873 | 7,626,133 | 10,278,701 | 236,410,123 |
| -1 | -23 | -31 | -251 | -713 | -1,321 | -5,773 | -7,781 | -30,383 | -40,951 | -178,963 | -331,571 | -941,873 | -7,626,133 | -10,278,701 | -236,410,123 |
