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 3,222,125, 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 | 3,222,125 | |
| -1 | -3,222,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,222,125.
Example:
1 x 3,222,125 = 3,222,125
and
-1 x -3,222,125 = 3,222,125
Notice both answers equal 3,222,125
With that explanation out of the way, let's continue. Next, we take the number 3,222,125 and divide it by 2:
3,222,125 ÷ 2 = 1,611,062.5
If the quotient is a whole number, then 2 and 1,611,062.5 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 | 3,222,125 | |
| -1 | -3,222,125 |
Now, we try dividing 3,222,125 by 3:
3,222,125 ÷ 3 = 1,074,041.6667
If the quotient is a whole number, then 3 and 1,074,041.6667 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 | 3,222,125 | |
| -1 | -3,222,125 |
Let's try dividing by 4:
3,222,125 ÷ 4 = 805,531.25
If the quotient is a whole number, then 4 and 805,531.25 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 | 3,222,125 | |
| -1 | 3,222,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 149 | 173 | 745 | 865 | 3,725 | 4,325 | 18,625 | 21,625 | 25,777 | 128,885 | 644,425 | 3,222,125 |
| -1 | -5 | -25 | -125 | -149 | -173 | -745 | -865 | -3,725 | -4,325 | -18,625 | -21,625 | -25,777 | -128,885 | -644,425 | -3,222,125 |
