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 311,445,529, 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 | 311,445,529 | |
| -1 | -311,445,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,445,529.
Example:
1 x 311,445,529 = 311,445,529
and
-1 x -311,445,529 = 311,445,529
Notice both answers equal 311,445,529
With that explanation out of the way, let's continue. Next, we take the number 311,445,529 and divide it by 2:
311,445,529 ÷ 2 = 155,722,764.5
If the quotient is a whole number, then 2 and 155,722,764.5 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 | 311,445,529 | |
| -1 | -311,445,529 |
Now, we try dividing 311,445,529 by 3:
311,445,529 ÷ 3 = 103,815,176.3333
If the quotient is a whole number, then 3 and 103,815,176.3333 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 | 311,445,529 | |
| -1 | -311,445,529 |
Let's try dividing by 4:
311,445,529 ÷ 4 = 77,861,382.25
If the quotient is a whole number, then 4 and 77,861,382.25 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 | 311,445,529 | |
| -1 | 311,445,529 |
If you did it right, you will end up with this table:
| 1 | 29 | 103 | 127 | 821 | 2,987 | 3,683 | 13,081 | 23,809 | 84,563 | 104,267 | 379,349 | 2,452,327 | 3,023,743 | 10,739,501 | 311,445,529 |
| -1 | -29 | -103 | -127 | -821 | -2,987 | -3,683 | -13,081 | -23,809 | -84,563 | -104,267 | -379,349 | -2,452,327 | -3,023,743 | -10,739,501 | -311,445,529 |
