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 127,604,455, 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 | 127,604,455 | |
| -1 | -127,604,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 127,604,455.
Example:
1 x 127,604,455 = 127,604,455
and
-1 x -127,604,455 = 127,604,455
Notice both answers equal 127,604,455
With that explanation out of the way, let's continue. Next, we take the number 127,604,455 and divide it by 2:
127,604,455 ÷ 2 = 63,802,227.5
If the quotient is a whole number, then 2 and 63,802,227.5 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 | 127,604,455 | |
| -1 | -127,604,455 |
Now, we try dividing 127,604,455 by 3:
127,604,455 ÷ 3 = 42,534,818.3333
If the quotient is a whole number, then 3 and 42,534,818.3333 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 | 127,604,455 | |
| -1 | -127,604,455 |
Let's try dividing by 4:
127,604,455 ÷ 4 = 31,901,113.75
If the quotient is a whole number, then 4 and 31,901,113.75 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 | 127,604,455 | |
| -1 | 127,604,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 535 | 1,177 | 5,885 | 21,683 | 108,415 | 238,513 | 1,192,565 | 2,320,081 | 11,600,405 | 25,520,891 | 127,604,455 |
| -1 | -5 | -11 | -55 | -107 | -535 | -1,177 | -5,885 | -21,683 | -108,415 | -238,513 | -1,192,565 | -2,320,081 | -11,600,405 | -25,520,891 | -127,604,455 |
