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 4,222,255, 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 | 4,222,255 | |
| -1 | -4,222,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,222,255.
Example:
1 x 4,222,255 = 4,222,255
and
-1 x -4,222,255 = 4,222,255
Notice both answers equal 4,222,255
With that explanation out of the way, let's continue. Next, we take the number 4,222,255 and divide it by 2:
4,222,255 ÷ 2 = 2,111,127.5
If the quotient is a whole number, then 2 and 2,111,127.5 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 | 4,222,255 | |
| -1 | -4,222,255 |
Now, we try dividing 4,222,255 by 3:
4,222,255 ÷ 3 = 1,407,418.3333
If the quotient is a whole number, then 3 and 1,407,418.3333 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 | 4,222,255 | |
| -1 | -4,222,255 |
Let's try dividing by 4:
4,222,255 ÷ 4 = 1,055,563.75
If the quotient is a whole number, then 4 and 1,055,563.75 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 | 4,222,255 | |
| -1 | 4,222,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 787 | 1,073 | 3,935 | 5,365 | 22,823 | 29,119 | 114,115 | 145,595 | 844,451 | 4,222,255 |
| -1 | -5 | -29 | -37 | -145 | -185 | -787 | -1,073 | -3,935 | -5,365 | -22,823 | -29,119 | -114,115 | -145,595 | -844,451 | -4,222,255 |
