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 123,063,035, 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 | 123,063,035 | |
| -1 | -123,063,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,063,035.
Example:
1 x 123,063,035 = 123,063,035
and
-1 x -123,063,035 = 123,063,035
Notice both answers equal 123,063,035
With that explanation out of the way, let's continue. Next, we take the number 123,063,035 and divide it by 2:
123,063,035 ÷ 2 = 61,531,517.5
If the quotient is a whole number, then 2 and 61,531,517.5 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 | 123,063,035 | |
| -1 | -123,063,035 |
Now, we try dividing 123,063,035 by 3:
123,063,035 ÷ 3 = 41,021,011.6667
If the quotient is a whole number, then 3 and 41,021,011.6667 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 | 123,063,035 | |
| -1 | -123,063,035 |
Let's try dividing by 4:
123,063,035 ÷ 4 = 30,765,758.75
If the quotient is a whole number, then 4 and 30,765,758.75 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 | 123,063,035 | |
| -1 | 123,063,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 241 | 365 | 1,205 | 1,399 | 6,995 | 17,593 | 87,965 | 102,127 | 337,159 | 510,635 | 1,685,795 | 24,612,607 | 123,063,035 |
| -1 | -5 | -73 | -241 | -365 | -1,205 | -1,399 | -6,995 | -17,593 | -87,965 | -102,127 | -337,159 | -510,635 | -1,685,795 | -24,612,607 | -123,063,035 |
