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 1,555,015, 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 | 1,555,015 | |
| -1 | -1,555,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,555,015.
Example:
1 x 1,555,015 = 1,555,015
and
-1 x -1,555,015 = 1,555,015
Notice both answers equal 1,555,015
With that explanation out of the way, let's continue. Next, we take the number 1,555,015 and divide it by 2:
1,555,015 ÷ 2 = 777,507.5
If the quotient is a whole number, then 2 and 777,507.5 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 | 1,555,015 | |
| -1 | -1,555,015 |
Now, we try dividing 1,555,015 by 3:
1,555,015 ÷ 3 = 518,338.3333
If the quotient is a whole number, then 3 and 518,338.3333 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 | 1,555,015 | |
| -1 | -1,555,015 |
Let's try dividing by 4:
1,555,015 ÷ 4 = 388,753.75
If the quotient is a whole number, then 4 and 388,753.75 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 | 1,555,015 | |
| -1 | 1,555,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 577 | 2,695 | 2,885 | 4,039 | 6,347 | 20,195 | 28,273 | 31,735 | 44,429 | 141,365 | 222,145 | 311,003 | 1,555,015 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -577 | -2,695 | -2,885 | -4,039 | -6,347 | -20,195 | -28,273 | -31,735 | -44,429 | -141,365 | -222,145 | -311,003 | -1,555,015 |
