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 324,432,205, 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 | 324,432,205 | |
| -1 | -324,432,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,432,205.
Example:
1 x 324,432,205 = 324,432,205
and
-1 x -324,432,205 = 324,432,205
Notice both answers equal 324,432,205
With that explanation out of the way, let's continue. Next, we take the number 324,432,205 and divide it by 2:
324,432,205 ÷ 2 = 162,216,102.5
If the quotient is a whole number, then 2 and 162,216,102.5 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 | 324,432,205 | |
| -1 | -324,432,205 |
Now, we try dividing 324,432,205 by 3:
324,432,205 ÷ 3 = 108,144,068.3333
If the quotient is a whole number, then 3 and 108,144,068.3333 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 | 324,432,205 | |
| -1 | -324,432,205 |
Let's try dividing by 4:
324,432,205 ÷ 4 = 81,108,051.25
If the quotient is a whole number, then 4 and 81,108,051.25 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 | 324,432,205 | |
| -1 | 324,432,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 43 | 155 | 215 | 1,333 | 6,665 | 48,677 | 243,385 | 1,508,987 | 2,093,111 | 7,544,935 | 10,465,555 | 64,886,441 | 324,432,205 |
| -1 | -5 | -31 | -43 | -155 | -215 | -1,333 | -6,665 | -48,677 | -243,385 | -1,508,987 | -2,093,111 | -7,544,935 | -10,465,555 | -64,886,441 | -324,432,205 |
