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 122,403,235, 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 | 122,403,235 | |
| -1 | -122,403,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,403,235.
Example:
1 x 122,403,235 = 122,403,235
and
-1 x -122,403,235 = 122,403,235
Notice both answers equal 122,403,235
With that explanation out of the way, let's continue. Next, we take the number 122,403,235 and divide it by 2:
122,403,235 ÷ 2 = 61,201,617.5
If the quotient is a whole number, then 2 and 61,201,617.5 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 | 122,403,235 | |
| -1 | -122,403,235 |
Now, we try dividing 122,403,235 by 3:
122,403,235 ÷ 3 = 40,801,078.3333
If the quotient is a whole number, then 3 and 40,801,078.3333 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 | 122,403,235 | |
| -1 | -122,403,235 |
Let's try dividing by 4:
122,403,235 ÷ 4 = 30,600,808.75
If the quotient is a whole number, then 4 and 30,600,808.75 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 | 122,403,235 | |
| -1 | 122,403,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 127 | 265 | 635 | 3,637 | 6,731 | 18,185 | 33,655 | 192,761 | 461,899 | 963,805 | 2,309,495 | 24,480,647 | 122,403,235 |
| -1 | -5 | -53 | -127 | -265 | -635 | -3,637 | -6,731 | -18,185 | -33,655 | -192,761 | -461,899 | -963,805 | -2,309,495 | -24,480,647 | -122,403,235 |
