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 122,323,315, 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 | 122,323,315 | |
| -1 | -122,323,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,323,315.
Example:
1 x 122,323,315 = 122,323,315
and
-1 x -122,323,315 = 122,323,315
Notice both answers equal 122,323,315
With that explanation out of the way, let's continue. Next, we take the number 122,323,315 and divide it by 2:
122,323,315 ÷ 2 = 61,161,657.5
If the quotient is a whole number, then 2 and 61,161,657.5 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 | 122,323,315 | |
| -1 | -122,323,315 |
Now, we try dividing 122,323,315 by 3:
122,323,315 ÷ 3 = 40,774,438.3333
If the quotient is a whole number, then 3 and 40,774,438.3333 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 | 122,323,315 | |
| -1 | -122,323,315 |
Let's try dividing by 4:
122,323,315 ÷ 4 = 30,580,828.75
If the quotient is a whole number, then 4 and 30,580,828.75 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 | 122,323,315 | |
| -1 | 122,323,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 103 | 115 | 449 | 515 | 529 | 2,245 | 2,369 | 2,645 | 10,327 | 11,845 | 46,247 | 51,635 | 54,487 | 231,235 | 237,521 | 272,435 | 1,063,681 | 1,187,605 | 5,318,405 | 24,464,663 | 122,323,315 |
| -1 | -5 | -23 | -103 | -115 | -449 | -515 | -529 | -2,245 | -2,369 | -2,645 | -10,327 | -11,845 | -46,247 | -51,635 | -54,487 | -231,235 | -237,521 | -272,435 | -1,063,681 | -1,187,605 | -5,318,405 | -24,464,663 | -122,323,315 |
