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 4,511,255, 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 | 4,511,255 | |
| -1 | -4,511,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,511,255.
Example:
1 x 4,511,255 = 4,511,255
and
-1 x -4,511,255 = 4,511,255
Notice both answers equal 4,511,255
With that explanation out of the way, let's continue. Next, we take the number 4,511,255 and divide it by 2:
4,511,255 ÷ 2 = 2,255,627.5
If the quotient is a whole number, then 2 and 2,255,627.5 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 | 4,511,255 | |
| -1 | -4,511,255 |
Now, we try dividing 4,511,255 by 3:
4,511,255 ÷ 3 = 1,503,751.6667
If the quotient is a whole number, then 3 and 1,503,751.6667 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 | 4,511,255 | |
| -1 | -4,511,255 |
Let's try dividing by 4:
4,511,255 ÷ 4 = 1,127,813.75
If the quotient is a whole number, then 4 and 1,127,813.75 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 | 4,511,255 | |
| -1 | 4,511,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 2,113 | 2,135 | 10,565 | 14,791 | 73,955 | 128,893 | 644,465 | 902,251 | 4,511,255 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -2,113 | -2,135 | -10,565 | -14,791 | -73,955 | -128,893 | -644,465 | -902,251 | -4,511,255 |
