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 424,056,655, 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 | 424,056,655 | |
| -1 | -424,056,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 424,056,655.
Example:
1 x 424,056,655 = 424,056,655
and
-1 x -424,056,655 = 424,056,655
Notice both answers equal 424,056,655
With that explanation out of the way, let's continue. Next, we take the number 424,056,655 and divide it by 2:
424,056,655 ÷ 2 = 212,028,327.5
If the quotient is a whole number, then 2 and 212,028,327.5 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 | 424,056,655 | |
| -1 | -424,056,655 |
Now, we try dividing 424,056,655 by 3:
424,056,655 ÷ 3 = 141,352,218.3333
If the quotient is a whole number, then 3 and 141,352,218.3333 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 | 424,056,655 | |
| -1 | -424,056,655 |
Let's try dividing by 4:
424,056,655 ÷ 4 = 106,014,163.75
If the quotient is a whole number, then 4 and 106,014,163.75 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 | 424,056,655 | |
| -1 | 424,056,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 827 | 4,135 | 9,097 | 9,323 | 45,485 | 46,615 | 102,553 | 512,765 | 7,710,121 | 38,550,605 | 84,811,331 | 424,056,655 |
| -1 | -5 | -11 | -55 | -827 | -4,135 | -9,097 | -9,323 | -45,485 | -46,615 | -102,553 | -512,765 | -7,710,121 | -38,550,605 | -84,811,331 | -424,056,655 |
