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 122,317,565, 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 | 122,317,565 | |
| -1 | -122,317,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,317,565.
Example:
1 x 122,317,565 = 122,317,565
and
-1 x -122,317,565 = 122,317,565
Notice both answers equal 122,317,565
With that explanation out of the way, let's continue. Next, we take the number 122,317,565 and divide it by 2:
122,317,565 ÷ 2 = 61,158,782.5
If the quotient is a whole number, then 2 and 61,158,782.5 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 | 122,317,565 | |
| -1 | -122,317,565 |
Now, we try dividing 122,317,565 by 3:
122,317,565 ÷ 3 = 40,772,521.6667
If the quotient is a whole number, then 3 and 40,772,521.6667 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 | 122,317,565 | |
| -1 | -122,317,565 |
Let's try dividing by 4:
122,317,565 ÷ 4 = 30,579,391.25
If the quotient is a whole number, then 4 and 30,579,391.25 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 | 122,317,565 | |
| -1 | 122,317,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 101 | 115 | 505 | 2,323 | 10,531 | 11,615 | 52,655 | 242,213 | 1,063,631 | 1,211,065 | 5,318,155 | 24,463,513 | 122,317,565 |
| -1 | -5 | -23 | -101 | -115 | -505 | -2,323 | -10,531 | -11,615 | -52,655 | -242,213 | -1,063,631 | -1,211,065 | -5,318,155 | -24,463,513 | -122,317,565 |
