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 311,002,223, 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 | 311,002,223 | |
| -1 | -311,002,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,002,223.
Example:
1 x 311,002,223 = 311,002,223
and
-1 x -311,002,223 = 311,002,223
Notice both answers equal 311,002,223
With that explanation out of the way, let's continue. Next, we take the number 311,002,223 and divide it by 2:
311,002,223 ÷ 2 = 155,501,111.5
If the quotient is a whole number, then 2 and 155,501,111.5 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 | 311,002,223 | |
| -1 | -311,002,223 |
Now, we try dividing 311,002,223 by 3:
311,002,223 ÷ 3 = 103,667,407.6667
If the quotient is a whole number, then 3 and 103,667,407.6667 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 | 311,002,223 | |
| -1 | -311,002,223 |
Let's try dividing by 4:
311,002,223 ÷ 4 = 77,750,555.75
If the quotient is a whole number, then 4 and 77,750,555.75 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 | 311,002,223 | |
| -1 | 311,002,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 79 | 89 | 497 | 553 | 623 | 5,609 | 6,319 | 7,031 | 7,921 | 39,263 | 44,233 | 49,217 | 55,447 | 499,201 | 562,391 | 625,759 | 3,494,407 | 3,936,737 | 4,380,313 | 44,428,889 | 311,002,223 |
| -1 | -7 | -71 | -79 | -89 | -497 | -553 | -623 | -5,609 | -6,319 | -7,031 | -7,921 | -39,263 | -44,233 | -49,217 | -55,447 | -499,201 | -562,391 | -625,759 | -3,494,407 | -3,936,737 | -4,380,313 | -44,428,889 | -311,002,223 |
