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 3,002,545, 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 | 3,002,545 | |
| -1 | -3,002,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,002,545.
Example:
1 x 3,002,545 = 3,002,545
and
-1 x -3,002,545 = 3,002,545
Notice both answers equal 3,002,545
With that explanation out of the way, let's continue. Next, we take the number 3,002,545 and divide it by 2:
3,002,545 ÷ 2 = 1,501,272.5
If the quotient is a whole number, then 2 and 1,501,272.5 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 | 3,002,545 | |
| -1 | -3,002,545 |
Now, we try dividing 3,002,545 by 3:
3,002,545 ÷ 3 = 1,000,848.3333
If the quotient is a whole number, then 3 and 1,000,848.3333 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 | 3,002,545 | |
| -1 | -3,002,545 |
Let's try dividing by 4:
3,002,545 ÷ 4 = 750,636.25
If the quotient is a whole number, then 4 and 750,636.25 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 | 3,002,545 | |
| -1 | 3,002,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 6,599 | 32,995 | 46,193 | 85,787 | 230,965 | 428,935 | 600,509 | 3,002,545 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -6,599 | -32,995 | -46,193 | -85,787 | -230,965 | -428,935 | -600,509 | -3,002,545 |
