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 3,240,127, 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 | 3,240,127 | |
| -1 | -3,240,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,240,127.
Example:
1 x 3,240,127 = 3,240,127
and
-1 x -3,240,127 = 3,240,127
Notice both answers equal 3,240,127
With that explanation out of the way, let's continue. Next, we take the number 3,240,127 and divide it by 2:
3,240,127 ÷ 2 = 1,620,063.5
If the quotient is a whole number, then 2 and 1,620,063.5 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 | 3,240,127 | |
| -1 | -3,240,127 |
Now, we try dividing 3,240,127 by 3:
3,240,127 ÷ 3 = 1,080,042.3333
If the quotient is a whole number, then 3 and 1,080,042.3333 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 | 3,240,127 | |
| -1 | -3,240,127 |
Let's try dividing by 4:
3,240,127 ÷ 4 = 810,031.75
If the quotient is a whole number, then 4 and 810,031.75 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 | 3,240,127 | |
| -1 | 3,240,127 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 37 | 209 | 407 | 419 | 703 | 4,609 | 7,733 | 7,961 | 15,503 | 87,571 | 170,533 | 294,557 | 3,240,127 |
| -1 | -11 | -19 | -37 | -209 | -407 | -419 | -703 | -4,609 | -7,733 | -7,961 | -15,503 | -87,571 | -170,533 | -294,557 | -3,240,127 |
