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 324,113,155, 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 | 324,113,155 | |
| -1 | -324,113,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,113,155.
Example:
1 x 324,113,155 = 324,113,155
and
-1 x -324,113,155 = 324,113,155
Notice both answers equal 324,113,155
With that explanation out of the way, let's continue. Next, we take the number 324,113,155 and divide it by 2:
324,113,155 ÷ 2 = 162,056,577.5
If the quotient is a whole number, then 2 and 162,056,577.5 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 | 324,113,155 | |
| -1 | -324,113,155 |
Now, we try dividing 324,113,155 by 3:
324,113,155 ÷ 3 = 108,037,718.3333
If the quotient is a whole number, then 3 and 108,037,718.3333 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 | 324,113,155 | |
| -1 | -324,113,155 |
Let's try dividing by 4:
324,113,155 ÷ 4 = 81,028,288.75
If the quotient is a whole number, then 4 and 81,028,288.75 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 | 324,113,155 | |
| -1 | 324,113,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 157 | 185 | 785 | 5,809 | 11,159 | 29,045 | 55,795 | 412,883 | 1,751,963 | 2,064,415 | 8,759,815 | 64,822,631 | 324,113,155 |
| -1 | -5 | -37 | -157 | -185 | -785 | -5,809 | -11,159 | -29,045 | -55,795 | -412,883 | -1,751,963 | -2,064,415 | -8,759,815 | -64,822,631 | -324,113,155 |
