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 4,226,255, 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 | 4,226,255 | |
| -1 | -4,226,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,226,255.
Example:
1 x 4,226,255 = 4,226,255
and
-1 x -4,226,255 = 4,226,255
Notice both answers equal 4,226,255
With that explanation out of the way, let's continue. Next, we take the number 4,226,255 and divide it by 2:
4,226,255 ÷ 2 = 2,113,127.5
If the quotient is a whole number, then 2 and 2,113,127.5 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 | 4,226,255 | |
| -1 | -4,226,255 |
Now, we try dividing 4,226,255 by 3:
4,226,255 ÷ 3 = 1,408,751.6667
If the quotient is a whole number, then 3 and 1,408,751.6667 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 | 4,226,255 | |
| -1 | -4,226,255 |
Let's try dividing by 4:
4,226,255 ÷ 4 = 1,056,563.75
If the quotient is a whole number, then 4 and 1,056,563.75 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 | 4,226,255 | |
| -1 | 4,226,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 215 | 473 | 1,787 | 2,365 | 8,935 | 19,657 | 76,841 | 98,285 | 384,205 | 845,251 | 4,226,255 |
| -1 | -5 | -11 | -43 | -55 | -215 | -473 | -1,787 | -2,365 | -8,935 | -19,657 | -76,841 | -98,285 | -384,205 | -845,251 | -4,226,255 |
