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 606,424,385, 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 | 606,424,385 | |
| -1 | -606,424,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 606,424,385.
Example:
1 x 606,424,385 = 606,424,385
and
-1 x -606,424,385 = 606,424,385
Notice both answers equal 606,424,385
With that explanation out of the way, let's continue. Next, we take the number 606,424,385 and divide it by 2:
606,424,385 ÷ 2 = 303,212,192.5
If the quotient is a whole number, then 2 and 303,212,192.5 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 | 606,424,385 | |
| -1 | -606,424,385 |
Now, we try dividing 606,424,385 by 3:
606,424,385 ÷ 3 = 202,141,461.6667
If the quotient is a whole number, then 3 and 202,141,461.6667 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 | 606,424,385 | |
| -1 | -606,424,385 |
Let's try dividing by 4:
606,424,385 ÷ 4 = 151,606,096.25
If the quotient is a whole number, then 4 and 151,606,096.25 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 | 606,424,385 | |
| -1 | 606,424,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 163 | 815 | 1,141 | 5,705 | 106,297 | 531,485 | 744,079 | 3,720,395 | 17,326,411 | 86,632,055 | 121,284,877 | 606,424,385 |
| -1 | -5 | -7 | -35 | -163 | -815 | -1,141 | -5,705 | -106,297 | -531,485 | -744,079 | -3,720,395 | -17,326,411 | -86,632,055 | -121,284,877 | -606,424,385 |
