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 423,501,067, 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 | 423,501,067 | |
| -1 | -423,501,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,501,067.
Example:
1 x 423,501,067 = 423,501,067
and
-1 x -423,501,067 = 423,501,067
Notice both answers equal 423,501,067
With that explanation out of the way, let's continue. Next, we take the number 423,501,067 and divide it by 2:
423,501,067 ÷ 2 = 211,750,533.5
If the quotient is a whole number, then 2 and 211,750,533.5 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 | 423,501,067 | |
| -1 | -423,501,067 |
Now, we try dividing 423,501,067 by 3:
423,501,067 ÷ 3 = 141,167,022.3333
If the quotient is a whole number, then 3 and 141,167,022.3333 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 | 423,501,067 | |
| -1 | -423,501,067 |
Let's try dividing by 4:
423,501,067 ÷ 4 = 105,875,266.75
If the quotient is a whole number, then 4 and 105,875,266.75 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 | 423,501,067 | |
| -1 | 423,501,067 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 79 | 517 | 869 | 3,713 | 10,369 | 40,843 | 114,059 | 487,343 | 819,151 | 5,360,773 | 9,010,661 | 38,500,097 | 423,501,067 |
| -1 | -11 | -47 | -79 | -517 | -869 | -3,713 | -10,369 | -40,843 | -114,059 | -487,343 | -819,151 | -5,360,773 | -9,010,661 | -38,500,097 | -423,501,067 |
