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 3,100,559, 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 | 3,100,559 | |
| -1 | -3,100,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,100,559.
Example:
1 x 3,100,559 = 3,100,559
and
-1 x -3,100,559 = 3,100,559
Notice both answers equal 3,100,559
With that explanation out of the way, let's continue. Next, we take the number 3,100,559 and divide it by 2:
3,100,559 ÷ 2 = 1,550,279.5
If the quotient is a whole number, then 2 and 1,550,279.5 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 | 3,100,559 | |
| -1 | -3,100,559 |
Now, we try dividing 3,100,559 by 3:
3,100,559 ÷ 3 = 1,033,519.6667
If the quotient is a whole number, then 3 and 1,033,519.6667 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 | 3,100,559 | |
| -1 | -3,100,559 |
Let's try dividing by 4:
3,100,559 ÷ 4 = 775,139.75
If the quotient is a whole number, then 4 and 775,139.75 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 | 3,100,559 | |
| -1 | 3,100,559 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 469 | 601 | 737 | 4,207 | 5,159 | 6,611 | 40,267 | 46,277 | 281,869 | 442,937 | 3,100,559 |
| -1 | -7 | -11 | -67 | -77 | -469 | -601 | -737 | -4,207 | -5,159 | -6,611 | -40,267 | -46,277 | -281,869 | -442,937 | -3,100,559 |
