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 314,391,341, 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 | 314,391,341 | |
| -1 | -314,391,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 314,391,341.
Example:
1 x 314,391,341 = 314,391,341
and
-1 x -314,391,341 = 314,391,341
Notice both answers equal 314,391,341
With that explanation out of the way, let's continue. Next, we take the number 314,391,341 and divide it by 2:
314,391,341 ÷ 2 = 157,195,670.5
If the quotient is a whole number, then 2 and 157,195,670.5 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 | 314,391,341 | |
| -1 | -314,391,341 |
Now, we try dividing 314,391,341 by 3:
314,391,341 ÷ 3 = 104,797,113.6667
If the quotient is a whole number, then 3 and 104,797,113.6667 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 | 314,391,341 | |
| -1 | -314,391,341 |
Let's try dividing by 4:
314,391,341 ÷ 4 = 78,597,835.25
If the quotient is a whole number, then 4 and 78,597,835.25 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 | 314,391,341 | |
| -1 | 314,391,341 |
If you did it right, you will end up with this table:
| 1 | 11 | 149 | 433 | 443 | 1,639 | 4,763 | 4,873 | 64,517 | 66,007 | 191,819 | 709,687 | 726,077 | 2,110,009 | 28,581,031 | 314,391,341 |
| -1 | -11 | -149 | -433 | -443 | -1,639 | -4,763 | -4,873 | -64,517 | -66,007 | -191,819 | -709,687 | -726,077 | -2,110,009 | -28,581,031 | -314,391,341 |
