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 122,035,315, 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 | 122,035,315 | |
| -1 | -122,035,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,035,315.
Example:
1 x 122,035,315 = 122,035,315
and
-1 x -122,035,315 = 122,035,315
Notice both answers equal 122,035,315
With that explanation out of the way, let's continue. Next, we take the number 122,035,315 and divide it by 2:
122,035,315 ÷ 2 = 61,017,657.5
If the quotient is a whole number, then 2 and 61,017,657.5 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 | 122,035,315 | |
| -1 | -122,035,315 |
Now, we try dividing 122,035,315 by 3:
122,035,315 ÷ 3 = 40,678,438.3333
If the quotient is a whole number, then 3 and 40,678,438.3333 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 | 122,035,315 | |
| -1 | -122,035,315 |
Let's try dividing by 4:
122,035,315 ÷ 4 = 30,508,828.75
If the quotient is a whole number, then 4 and 30,508,828.75 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 | 122,035,315 | |
| -1 | 122,035,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 157 | 415 | 785 | 1,873 | 9,365 | 13,031 | 65,155 | 155,459 | 294,061 | 777,295 | 1,470,305 | 24,407,063 | 122,035,315 |
| -1 | -5 | -83 | -157 | -415 | -785 | -1,873 | -9,365 | -13,031 | -65,155 | -155,459 | -294,061 | -777,295 | -1,470,305 | -24,407,063 | -122,035,315 |
