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 324,011,051, 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 | 324,011,051 | |
| -1 | -324,011,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,011,051.
Example:
1 x 324,011,051 = 324,011,051
and
-1 x -324,011,051 = 324,011,051
Notice both answers equal 324,011,051
With that explanation out of the way, let's continue. Next, we take the number 324,011,051 and divide it by 2:
324,011,051 ÷ 2 = 162,005,525.5
If the quotient is a whole number, then 2 and 162,005,525.5 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 | 324,011,051 | |
| -1 | -324,011,051 |
Now, we try dividing 324,011,051 by 3:
324,011,051 ÷ 3 = 108,003,683.6667
If the quotient is a whole number, then 3 and 108,003,683.6667 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 | 324,011,051 | |
| -1 | -324,011,051 |
Let's try dividing by 4:
324,011,051 ÷ 4 = 81,002,762.75
If the quotient is a whole number, then 4 and 81,002,762.75 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 | 324,011,051 | |
| -1 | 324,011,051 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 2,093 | 154,807 | 1,083,649 | 2,012,491 | 3,560,561 | 14,087,437 | 24,923,927 | 46,287,293 | 324,011,051 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -2,093 | -154,807 | -1,083,649 | -2,012,491 | -3,560,561 | -14,087,437 | -24,923,927 | -46,287,293 | -324,011,051 |
