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 605,420,063, 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 | 605,420,063 | |
| -1 | -605,420,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,420,063.
Example:
1 x 605,420,063 = 605,420,063
and
-1 x -605,420,063 = 605,420,063
Notice both answers equal 605,420,063
With that explanation out of the way, let's continue. Next, we take the number 605,420,063 and divide it by 2:
605,420,063 ÷ 2 = 302,710,031.5
If the quotient is a whole number, then 2 and 302,710,031.5 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 | 605,420,063 | |
| -1 | -605,420,063 |
Now, we try dividing 605,420,063 by 3:
605,420,063 ÷ 3 = 201,806,687.6667
If the quotient is a whole number, then 3 and 201,806,687.6667 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 | 605,420,063 | |
| -1 | -605,420,063 |
Let's try dividing by 4:
605,420,063 ÷ 4 = 151,355,015.75
If the quotient is a whole number, then 4 and 151,355,015.75 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 | 605,420,063 | |
| -1 | 605,420,063 |
If you did it right, you will end up with this table:
| 1 | 41 | 59 | 353 | 709 | 2,419 | 14,473 | 20,827 | 29,069 | 41,831 | 250,277 | 853,907 | 1,715,071 | 10,261,357 | 14,766,343 | 605,420,063 |
| -1 | -41 | -59 | -353 | -709 | -2,419 | -14,473 | -20,827 | -29,069 | -41,831 | -250,277 | -853,907 | -1,715,071 | -10,261,357 | -14,766,343 | -605,420,063 |
