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 127,260,535, 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 | 127,260,535 | |
| -1 | -127,260,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 127,260,535.
Example:
1 x 127,260,535 = 127,260,535
and
-1 x -127,260,535 = 127,260,535
Notice both answers equal 127,260,535
With that explanation out of the way, let's continue. Next, we take the number 127,260,535 and divide it by 2:
127,260,535 ÷ 2 = 63,630,267.5
If the quotient is a whole number, then 2 and 63,630,267.5 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 | 127,260,535 | |
| -1 | -127,260,535 |
Now, we try dividing 127,260,535 by 3:
127,260,535 ÷ 3 = 42,420,178.3333
If the quotient is a whole number, then 3 and 42,420,178.3333 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 | 127,260,535 | |
| -1 | -127,260,535 |
Let's try dividing by 4:
127,260,535 ÷ 4 = 31,815,133.75
If the quotient is a whole number, then 4 and 31,815,133.75 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 | 127,260,535 | |
| -1 | 127,260,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 151 | 365 | 755 | 2,309 | 11,023 | 11,545 | 55,115 | 168,557 | 348,659 | 842,785 | 1,743,295 | 25,452,107 | 127,260,535 |
| -1 | -5 | -73 | -151 | -365 | -755 | -2,309 | -11,023 | -11,545 | -55,115 | -168,557 | -348,659 | -842,785 | -1,743,295 | -25,452,107 | -127,260,535 |
