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 122,132,335, 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 | 122,132,335 | |
| -1 | -122,132,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,132,335.
Example:
1 x 122,132,335 = 122,132,335
and
-1 x -122,132,335 = 122,132,335
Notice both answers equal 122,132,335
With that explanation out of the way, let's continue. Next, we take the number 122,132,335 and divide it by 2:
122,132,335 ÷ 2 = 61,066,167.5
If the quotient is a whole number, then 2 and 61,066,167.5 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 | 122,132,335 | |
| -1 | -122,132,335 |
Now, we try dividing 122,132,335 by 3:
122,132,335 ÷ 3 = 40,710,778.3333
If the quotient is a whole number, then 3 and 40,710,778.3333 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 | 122,132,335 | |
| -1 | -122,132,335 |
Let's try dividing by 4:
122,132,335 ÷ 4 = 30,533,083.75
If the quotient is a whole number, then 4 and 30,533,083.75 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 | 122,132,335 | |
| -1 | 122,132,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 110,527 | 552,635 | 1,436,851 | 1,878,959 | 7,184,255 | 9,394,795 | 24,426,467 | 122,132,335 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -110,527 | -552,635 | -1,436,851 | -1,878,959 | -7,184,255 | -9,394,795 | -24,426,467 | -122,132,335 |
