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 4,312,255, 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 | 4,312,255 | |
| -1 | -4,312,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,312,255.
Example:
1 x 4,312,255 = 4,312,255
and
-1 x -4,312,255 = 4,312,255
Notice both answers equal 4,312,255
With that explanation out of the way, let's continue. Next, we take the number 4,312,255 and divide it by 2:
4,312,255 ÷ 2 = 2,156,127.5
If the quotient is a whole number, then 2 and 2,156,127.5 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 | 4,312,255 | |
| -1 | -4,312,255 |
Now, we try dividing 4,312,255 by 3:
4,312,255 ÷ 3 = 1,437,418.3333
If the quotient is a whole number, then 3 and 1,437,418.3333 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 | 4,312,255 | |
| -1 | -4,312,255 |
Let's try dividing by 4:
4,312,255 ÷ 4 = 1,078,063.75
If the quotient is a whole number, then 4 and 1,078,063.75 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 | 4,312,255 | |
| -1 | 4,312,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 43 | 155 | 215 | 647 | 1,333 | 3,235 | 6,665 | 20,057 | 27,821 | 100,285 | 139,105 | 862,451 | 4,312,255 |
| -1 | -5 | -31 | -43 | -155 | -215 | -647 | -1,333 | -3,235 | -6,665 | -20,057 | -27,821 | -100,285 | -139,105 | -862,451 | -4,312,255 |
