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 511,010,453, 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 | 511,010,453 | |
| -1 | -511,010,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 511,010,453.
Example:
1 x 511,010,453 = 511,010,453
and
-1 x -511,010,453 = 511,010,453
Notice both answers equal 511,010,453
With that explanation out of the way, let's continue. Next, we take the number 511,010,453 and divide it by 2:
511,010,453 ÷ 2 = 255,505,226.5
If the quotient is a whole number, then 2 and 255,505,226.5 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 | 511,010,453 | |
| -1 | -511,010,453 |
Now, we try dividing 511,010,453 by 3:
511,010,453 ÷ 3 = 170,336,817.6667
If the quotient is a whole number, then 3 and 170,336,817.6667 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 | 511,010,453 | |
| -1 | -511,010,453 |
Let's try dividing by 4:
511,010,453 ÷ 4 = 127,752,613.25
If the quotient is a whole number, then 4 and 127,752,613.25 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 | 511,010,453 | |
| -1 | 511,010,453 |
If you did it right, you will end up with this table:
| 1 | 19 | 97 | 179 | 1,549 | 1,843 | 3,401 | 17,363 | 29,431 | 150,253 | 277,271 | 329,897 | 2,854,807 | 5,268,149 | 26,895,287 | 511,010,453 |
| -1 | -19 | -97 | -179 | -1,549 | -1,843 | -3,401 | -17,363 | -29,431 | -150,253 | -277,271 | -329,897 | -2,854,807 | -5,268,149 | -26,895,287 | -511,010,453 |
