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 310,000,445, 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 | 310,000,445 | |
| -1 | -310,000,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,000,445.
Example:
1 x 310,000,445 = 310,000,445
and
-1 x -310,000,445 = 310,000,445
Notice both answers equal 310,000,445
With that explanation out of the way, let's continue. Next, we take the number 310,000,445 and divide it by 2:
310,000,445 ÷ 2 = 155,000,222.5
If the quotient is a whole number, then 2 and 155,000,222.5 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 | 310,000,445 | |
| -1 | -310,000,445 |
Now, we try dividing 310,000,445 by 3:
310,000,445 ÷ 3 = 103,333,481.6667
If the quotient is a whole number, then 3 and 103,333,481.6667 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 | 310,000,445 | |
| -1 | -310,000,445 |
Let's try dividing by 4:
310,000,445 ÷ 4 = 77,500,111.25
If the quotient is a whole number, then 4 and 77,500,111.25 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 | 310,000,445 | |
| -1 | 310,000,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 719 | 1,627 | 3,595 | 8,135 | 38,107 | 86,231 | 190,535 | 431,155 | 1,169,813 | 5,849,065 | 62,000,089 | 310,000,445 |
| -1 | -5 | -53 | -265 | -719 | -1,627 | -3,595 | -8,135 | -38,107 | -86,231 | -190,535 | -431,155 | -1,169,813 | -5,849,065 | -62,000,089 | -310,000,445 |
