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 423,420,011, 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 | 423,420,011 | |
| -1 | -423,420,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,420,011.
Example:
1 x 423,420,011 = 423,420,011
and
-1 x -423,420,011 = 423,420,011
Notice both answers equal 423,420,011
With that explanation out of the way, let's continue. Next, we take the number 423,420,011 and divide it by 2:
423,420,011 ÷ 2 = 211,710,005.5
If the quotient is a whole number, then 2 and 211,710,005.5 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 | 423,420,011 | |
| -1 | -423,420,011 |
Now, we try dividing 423,420,011 by 3:
423,420,011 ÷ 3 = 141,140,003.6667
If the quotient is a whole number, then 3 and 141,140,003.6667 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 | 423,420,011 | |
| -1 | -423,420,011 |
Let's try dividing by 4:
423,420,011 ÷ 4 = 105,855,002.75
If the quotient is a whole number, then 4 and 105,855,002.75 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 | 423,420,011 | |
| -1 | 423,420,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 301 | 367 | 2,569 | 3,833 | 15,781 | 26,831 | 110,467 | 164,819 | 1,153,733 | 1,406,711 | 9,846,977 | 60,488,573 | 423,420,011 |
| -1 | -7 | -43 | -301 | -367 | -2,569 | -3,833 | -15,781 | -26,831 | -110,467 | -164,819 | -1,153,733 | -1,406,711 | -9,846,977 | -60,488,573 | -423,420,011 |
