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 322,021,225, 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 | 322,021,225 | |
| -1 | -322,021,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,021,225.
Example:
1 x 322,021,225 = 322,021,225
and
-1 x -322,021,225 = 322,021,225
Notice both answers equal 322,021,225
With that explanation out of the way, let's continue. Next, we take the number 322,021,225 and divide it by 2:
322,021,225 ÷ 2 = 161,010,612.5
If the quotient is a whole number, then 2 and 161,010,612.5 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 | 322,021,225 | |
| -1 | -322,021,225 |
Now, we try dividing 322,021,225 by 3:
322,021,225 ÷ 3 = 107,340,408.3333
If the quotient is a whole number, then 3 and 107,340,408.3333 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 | 322,021,225 | |
| -1 | -322,021,225 |
Let's try dividing by 4:
322,021,225 ÷ 4 = 80,505,306.25
If the quotient is a whole number, then 4 and 80,505,306.25 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 | 322,021,225 | |
| -1 | 322,021,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 191 | 425 | 955 | 3,247 | 3,967 | 4,775 | 16,235 | 19,835 | 67,439 | 81,175 | 99,175 | 337,195 | 757,697 | 1,685,975 | 3,788,485 | 12,880,849 | 18,942,425 | 64,404,245 | 322,021,225 |
| -1 | -5 | -17 | -25 | -85 | -191 | -425 | -955 | -3,247 | -3,967 | -4,775 | -16,235 | -19,835 | -67,439 | -81,175 | -99,175 | -337,195 | -757,697 | -1,685,975 | -3,788,485 | -12,880,849 | -18,942,425 | -64,404,245 | -322,021,225 |
