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 605,512,651, 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 | 605,512,651 | |
| -1 | -605,512,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,512,651.
Example:
1 x 605,512,651 = 605,512,651
and
-1 x -605,512,651 = 605,512,651
Notice both answers equal 605,512,651
With that explanation out of the way, let's continue. Next, we take the number 605,512,651 and divide it by 2:
605,512,651 ÷ 2 = 302,756,325.5
If the quotient is a whole number, then 2 and 302,756,325.5 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 | 605,512,651 | |
| -1 | -605,512,651 |
Now, we try dividing 605,512,651 by 3:
605,512,651 ÷ 3 = 201,837,550.3333
If the quotient is a whole number, then 3 and 201,837,550.3333 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 | 605,512,651 | |
| -1 | -605,512,651 |
Let's try dividing by 4:
605,512,651 ÷ 4 = 151,378,162.75
If the quotient is a whole number, then 4 and 151,378,162.75 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 | 605,512,651 | |
| -1 | 605,512,651 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 251 | 1,219 | 1,979 | 5,773 | 13,303 | 45,517 | 104,887 | 305,969 | 496,729 | 2,412,401 | 11,424,767 | 26,326,637 | 605,512,651 |
| -1 | -23 | -53 | -251 | -1,219 | -1,979 | -5,773 | -13,303 | -45,517 | -104,887 | -305,969 | -496,729 | -2,412,401 | -11,424,767 | -26,326,637 | -605,512,651 |
