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 3,062,255, 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 | 3,062,255 | |
| -1 | -3,062,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,062,255.
Example:
1 x 3,062,255 = 3,062,255
and
-1 x -3,062,255 = 3,062,255
Notice both answers equal 3,062,255
With that explanation out of the way, let's continue. Next, we take the number 3,062,255 and divide it by 2:
3,062,255 ÷ 2 = 1,531,127.5
If the quotient is a whole number, then 2 and 1,531,127.5 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 | 3,062,255 | |
| -1 | -3,062,255 |
Now, we try dividing 3,062,255 by 3:
3,062,255 ÷ 3 = 1,020,751.6667
If the quotient is a whole number, then 3 and 1,020,751.6667 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 | 3,062,255 | |
| -1 | -3,062,255 |
Let's try dividing by 4:
3,062,255 ÷ 4 = 765,563.75
If the quotient is a whole number, then 4 and 765,563.75 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 | 3,062,255 | |
| -1 | 3,062,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 49 | 145 | 203 | 245 | 431 | 1,015 | 1,421 | 2,155 | 3,017 | 7,105 | 12,499 | 15,085 | 21,119 | 62,495 | 87,493 | 105,595 | 437,465 | 612,451 | 3,062,255 |
| -1 | -5 | -7 | -29 | -35 | -49 | -145 | -203 | -245 | -431 | -1,015 | -1,421 | -2,155 | -3,017 | -7,105 | -12,499 | -15,085 | -21,119 | -62,495 | -87,493 | -105,595 | -437,465 | -612,451 | -3,062,255 |
