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 423,331,415, 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 | 423,331,415 | |
| -1 | -423,331,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,331,415.
Example:
1 x 423,331,415 = 423,331,415
and
-1 x -423,331,415 = 423,331,415
Notice both answers equal 423,331,415
With that explanation out of the way, let's continue. Next, we take the number 423,331,415 and divide it by 2:
423,331,415 ÷ 2 = 211,665,707.5
If the quotient is a whole number, then 2 and 211,665,707.5 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 | 423,331,415 | |
| -1 | -423,331,415 |
Now, we try dividing 423,331,415 by 3:
423,331,415 ÷ 3 = 141,110,471.6667
If the quotient is a whole number, then 3 and 141,110,471.6667 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 | 423,331,415 | |
| -1 | -423,331,415 |
Let's try dividing by 4:
423,331,415 ÷ 4 = 105,832,853.75
If the quotient is a whole number, then 4 and 105,832,853.75 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 | 423,331,415 | |
| -1 | 423,331,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 1,885 | 224,579 | 1,122,895 | 2,919,527 | 6,512,791 | 14,597,635 | 32,563,955 | 84,666,283 | 423,331,415 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -1,885 | -224,579 | -1,122,895 | -2,919,527 | -6,512,791 | -14,597,635 | -32,563,955 | -84,666,283 | -423,331,415 |
