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 650,270,209, 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 | 650,270,209 | |
| -1 | -650,270,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 650,270,209.
Example:
1 x 650,270,209 = 650,270,209
and
-1 x -650,270,209 = 650,270,209
Notice both answers equal 650,270,209
With that explanation out of the way, let's continue. Next, we take the number 650,270,209 and divide it by 2:
650,270,209 ÷ 2 = 325,135,104.5
If the quotient is a whole number, then 2 and 325,135,104.5 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 | 650,270,209 | |
| -1 | -650,270,209 |
Now, we try dividing 650,270,209 by 3:
650,270,209 ÷ 3 = 216,756,736.3333
If the quotient is a whole number, then 3 and 216,756,736.3333 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 | 650,270,209 | |
| -1 | -650,270,209 |
Let's try dividing by 4:
650,270,209 ÷ 4 = 162,567,552.25
If the quotient is a whole number, then 4 and 162,567,552.25 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 | 650,270,209 | |
| -1 | 650,270,209 |
If you did it right, you will end up with this table:
| 1 | 41 | 43 | 103 | 1,763 | 3,581 | 4,223 | 4,429 | 146,821 | 153,983 | 181,589 | 368,843 | 6,313,303 | 15,122,563 | 15,860,249 | 650,270,209 |
| -1 | -41 | -43 | -103 | -1,763 | -3,581 | -4,223 | -4,429 | -146,821 | -153,983 | -181,589 | -368,843 | -6,313,303 | -15,122,563 | -15,860,249 | -650,270,209 |
