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 322,031,437, 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 | 322,031,437 | |
| -1 | -322,031,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,031,437.
Example:
1 x 322,031,437 = 322,031,437
and
-1 x -322,031,437 = 322,031,437
Notice both answers equal 322,031,437
With that explanation out of the way, let's continue. Next, we take the number 322,031,437 and divide it by 2:
322,031,437 ÷ 2 = 161,015,718.5
If the quotient is a whole number, then 2 and 161,015,718.5 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 | 322,031,437 | |
| -1 | -322,031,437 |
Now, we try dividing 322,031,437 by 3:
322,031,437 ÷ 3 = 107,343,812.3333
If the quotient is a whole number, then 3 and 107,343,812.3333 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 | 322,031,437 | |
| -1 | -322,031,437 |
Let's try dividing by 4:
322,031,437 ÷ 4 = 80,507,859.25
If the quotient is a whole number, then 4 and 80,507,859.25 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 | 322,031,437 | |
| -1 | 322,031,437 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 186,253 | 1,303,771 | 2,421,289 | 3,538,807 | 16,949,023 | 24,771,649 | 46,004,491 | 322,031,437 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -186,253 | -1,303,771 | -2,421,289 | -3,538,807 | -16,949,023 | -24,771,649 | -46,004,491 | -322,031,437 |
