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 322,420,415, 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 | 322,420,415 | |
| -1 | -322,420,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,420,415.
Example:
1 x 322,420,415 = 322,420,415
and
-1 x -322,420,415 = 322,420,415
Notice both answers equal 322,420,415
With that explanation out of the way, let's continue. Next, we take the number 322,420,415 and divide it by 2:
322,420,415 ÷ 2 = 161,210,207.5
If the quotient is a whole number, then 2 and 161,210,207.5 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 | 322,420,415 | |
| -1 | -322,420,415 |
Now, we try dividing 322,420,415 by 3:
322,420,415 ÷ 3 = 107,473,471.6667
If the quotient is a whole number, then 3 and 107,473,471.6667 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 | 322,420,415 | |
| -1 | -322,420,415 |
Let's try dividing by 4:
322,420,415 ÷ 4 = 80,605,103.75
If the quotient is a whole number, then 4 and 80,605,103.75 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 | 322,420,415 | |
| -1 | 322,420,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 191 | 335 | 955 | 5,039 | 12,797 | 25,195 | 63,985 | 337,613 | 962,449 | 1,688,065 | 4,812,245 | 64,484,083 | 322,420,415 |
| -1 | -5 | -67 | -191 | -335 | -955 | -5,039 | -12,797 | -25,195 | -63,985 | -337,613 | -962,449 | -1,688,065 | -4,812,245 | -64,484,083 | -322,420,415 |
