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 123,060,365, 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 | 123,060,365 | |
| -1 | -123,060,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,060,365.
Example:
1 x 123,060,365 = 123,060,365
and
-1 x -123,060,365 = 123,060,365
Notice both answers equal 123,060,365
With that explanation out of the way, let's continue. Next, we take the number 123,060,365 and divide it by 2:
123,060,365 ÷ 2 = 61,530,182.5
If the quotient is a whole number, then 2 and 61,530,182.5 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 | 123,060,365 | |
| -1 | -123,060,365 |
Now, we try dividing 123,060,365 by 3:
123,060,365 ÷ 3 = 41,020,121.6667
If the quotient is a whole number, then 3 and 41,020,121.6667 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 | 123,060,365 | |
| -1 | -123,060,365 |
Let's try dividing by 4:
123,060,365 ÷ 4 = 30,765,091.25
If the quotient is a whole number, then 4 and 30,765,091.25 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 | 123,060,365 | |
| -1 | 123,060,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 83 | 85 | 415 | 1,411 | 7,055 | 17,443 | 87,215 | 296,531 | 1,447,769 | 1,482,655 | 7,238,845 | 24,612,073 | 123,060,365 |
| -1 | -5 | -17 | -83 | -85 | -415 | -1,411 | -7,055 | -17,443 | -87,215 | -296,531 | -1,447,769 | -1,482,655 | -7,238,845 | -24,612,073 | -123,060,365 |
