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 101,040,535, 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 | 101,040,535 | |
| -1 | -101,040,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,040,535.
Example:
1 x 101,040,535 = 101,040,535
and
-1 x -101,040,535 = 101,040,535
Notice both answers equal 101,040,535
With that explanation out of the way, let's continue. Next, we take the number 101,040,535 and divide it by 2:
101,040,535 ÷ 2 = 50,520,267.5
If the quotient is a whole number, then 2 and 50,520,267.5 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 | 101,040,535 | |
| -1 | -101,040,535 |
Now, we try dividing 101,040,535 by 3:
101,040,535 ÷ 3 = 33,680,178.3333
If the quotient is a whole number, then 3 and 33,680,178.3333 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 | 101,040,535 | |
| -1 | -101,040,535 |
Let's try dividing by 4:
101,040,535 ÷ 4 = 25,260,133.75
If the quotient is a whole number, then 4 and 25,260,133.75 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 | 101,040,535 | |
| -1 | 101,040,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 181 | 485 | 905 | 1,151 | 5,755 | 17,557 | 87,785 | 111,647 | 208,331 | 558,235 | 1,041,655 | 20,208,107 | 101,040,535 |
| -1 | -5 | -97 | -181 | -485 | -905 | -1,151 | -5,755 | -17,557 | -87,785 | -111,647 | -208,331 | -558,235 | -1,041,655 | -20,208,107 | -101,040,535 |
