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 432,021,022, 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 | 432,021,022 | |
| -1 | -432,021,022 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 432,021,022.
Example:
1 x 432,021,022 = 432,021,022
and
-1 x -432,021,022 = 432,021,022
Notice both answers equal 432,021,022
With that explanation out of the way, let's continue. Next, we take the number 432,021,022 and divide it by 2:
432,021,022 ÷ 2 = 216,010,511
If the quotient is a whole number, then 2 and 216,010,511 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 216,010,511 | 432,021,022 | |
| -1 | -2 | -216,010,511 | -432,021,022 |
Now, we try dividing 432,021,022 by 3:
432,021,022 ÷ 3 = 144,007,007.3333
If the quotient is a whole number, then 3 and 144,007,007.3333 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 | 2 | 216,010,511 | 432,021,022 | |
| -1 | -2 | -216,010,511 | -432,021,022 |
Let's try dividing by 4:
432,021,022 ÷ 4 = 108,005,255.5
If the quotient is a whole number, then 4 and 108,005,255.5 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 | 2 | 216,010,511 | 432,021,022 | |
| -1 | -2 | -216,010,511 | 432,021,022 |
If you did it right, you will end up with this table:
| 1 | 2 | 31 | 62 | 223 | 446 | 6,913 | 13,826 | 31,247 | 62,494 | 968,657 | 1,937,314 | 6,968,081 | 13,936,162 | 216,010,511 | 432,021,022 |
| -1 | -2 | -31 | -62 | -223 | -446 | -6,913 | -13,826 | -31,247 | -62,494 | -968,657 | -1,937,314 | -6,968,081 | -13,936,162 | -216,010,511 | -432,021,022 |
