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 212,441,327, 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 | 212,441,327 | |
| -1 | -212,441,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 212,441,327.
Example:
1 x 212,441,327 = 212,441,327
and
-1 x -212,441,327 = 212,441,327
Notice both answers equal 212,441,327
With that explanation out of the way, let's continue. Next, we take the number 212,441,327 and divide it by 2:
212,441,327 ÷ 2 = 106,220,663.5
If the quotient is a whole number, then 2 and 106,220,663.5 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 | 212,441,327 | |
| -1 | -212,441,327 |
Now, we try dividing 212,441,327 by 3:
212,441,327 ÷ 3 = 70,813,775.6667
If the quotient is a whole number, then 3 and 70,813,775.6667 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 | 212,441,327 | |
| -1 | -212,441,327 |
Let's try dividing by 4:
212,441,327 ÷ 4 = 53,110,331.75
If the quotient is a whole number, then 4 and 53,110,331.75 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 | 212,441,327 | |
| -1 | 212,441,327 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 109 | 203 | 763 | 3,161 | 9,601 | 22,127 | 67,207 | 278,429 | 1,046,509 | 1,949,003 | 7,325,563 | 30,348,761 | 212,441,327 |
| -1 | -7 | -29 | -109 | -203 | -763 | -3,161 | -9,601 | -22,127 | -67,207 | -278,429 | -1,046,509 | -1,949,003 | -7,325,563 | -30,348,761 | -212,441,327 |
