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 422,040,311, 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 | 422,040,311 | |
| -1 | -422,040,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 422,040,311.
Example:
1 x 422,040,311 = 422,040,311
and
-1 x -422,040,311 = 422,040,311
Notice both answers equal 422,040,311
With that explanation out of the way, let's continue. Next, we take the number 422,040,311 and divide it by 2:
422,040,311 ÷ 2 = 211,020,155.5
If the quotient is a whole number, then 2 and 211,020,155.5 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 | 422,040,311 | |
| -1 | -422,040,311 |
Now, we try dividing 422,040,311 by 3:
422,040,311 ÷ 3 = 140,680,103.6667
If the quotient is a whole number, then 3 and 140,680,103.6667 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 | 422,040,311 | |
| -1 | -422,040,311 |
Let's try dividing by 4:
422,040,311 ÷ 4 = 105,510,077.75
If the quotient is a whole number, then 4 and 105,510,077.75 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 | 422,040,311 | |
| -1 | 422,040,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,879 | 2,917 | 13,153 | 20,419 | 20,669 | 32,087 | 144,683 | 224,609 | 5,481,043 | 38,367,301 | 60,291,473 | 422,040,311 |
| -1 | -7 | -11 | -77 | -1,879 | -2,917 | -13,153 | -20,419 | -20,669 | -32,087 | -144,683 | -224,609 | -5,481,043 | -38,367,301 | -60,291,473 | -422,040,311 |
