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 3,042,545, 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 | 3,042,545 | |
| -1 | -3,042,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,042,545.
Example:
1 x 3,042,545 = 3,042,545
and
-1 x -3,042,545 = 3,042,545
Notice both answers equal 3,042,545
With that explanation out of the way, let's continue. Next, we take the number 3,042,545 and divide it by 2:
3,042,545 ÷ 2 = 1,521,272.5
If the quotient is a whole number, then 2 and 1,521,272.5 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 | 3,042,545 | |
| -1 | -3,042,545 |
Now, we try dividing 3,042,545 by 3:
3,042,545 ÷ 3 = 1,014,181.6667
If the quotient is a whole number, then 3 and 1,014,181.6667 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 | 3,042,545 | |
| -1 | -3,042,545 |
Let's try dividing by 4:
3,042,545 ÷ 4 = 760,636.25
If the quotient is a whole number, then 4 and 760,636.25 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 | 3,042,545 | |
| -1 | 3,042,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 107 | 121 | 235 | 517 | 535 | 605 | 1,177 | 2,585 | 5,029 | 5,687 | 5,885 | 12,947 | 25,145 | 28,435 | 55,319 | 64,735 | 276,595 | 608,509 | 3,042,545 |
| -1 | -5 | -11 | -47 | -55 | -107 | -121 | -235 | -517 | -535 | -605 | -1,177 | -2,585 | -5,029 | -5,687 | -5,885 | -12,947 | -25,145 | -28,435 | -55,319 | -64,735 | -276,595 | -608,509 | -3,042,545 |
