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 3,027,505, 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 | 3,027,505 | |
| -1 | -3,027,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,027,505.
Example:
1 x 3,027,505 = 3,027,505
and
-1 x -3,027,505 = 3,027,505
Notice both answers equal 3,027,505
With that explanation out of the way, let's continue. Next, we take the number 3,027,505 and divide it by 2:
3,027,505 ÷ 2 = 1,513,752.5
If the quotient is a whole number, then 2 and 1,513,752.5 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 | 3,027,505 | |
| -1 | -3,027,505 |
Now, we try dividing 3,027,505 by 3:
3,027,505 ÷ 3 = 1,009,168.3333
If the quotient is a whole number, then 3 and 1,009,168.3333 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 | 3,027,505 | |
| -1 | -3,027,505 |
Let's try dividing by 4:
3,027,505 ÷ 4 = 756,876.25
If the quotient is a whole number, then 4 and 756,876.25 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 | 3,027,505 | |
| -1 | 3,027,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 65 | 235 | 611 | 991 | 3,055 | 4,955 | 12,883 | 46,577 | 64,415 | 232,885 | 605,501 | 3,027,505 |
| -1 | -5 | -13 | -47 | -65 | -235 | -611 | -991 | -3,055 | -4,955 | -12,883 | -46,577 | -64,415 | -232,885 | -605,501 | -3,027,505 |
