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 4,784,945, 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 | 4,784,945 | |
| -1 | -4,784,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,784,945.
Example:
1 x 4,784,945 = 4,784,945
and
-1 x -4,784,945 = 4,784,945
Notice both answers equal 4,784,945
With that explanation out of the way, let's continue. Next, we take the number 4,784,945 and divide it by 2:
4,784,945 ÷ 2 = 2,392,472.5
If the quotient is a whole number, then 2 and 2,392,472.5 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 | 4,784,945 | |
| -1 | -4,784,945 |
Now, we try dividing 4,784,945 by 3:
4,784,945 ÷ 3 = 1,594,981.6667
If the quotient is a whole number, then 3 and 1,594,981.6667 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 | 4,784,945 | |
| -1 | -4,784,945 |
Let's try dividing by 4:
4,784,945 ÷ 4 = 1,196,236.25
If the quotient is a whole number, then 4 and 1,196,236.25 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 | 4,784,945 | |
| -1 | 4,784,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 605 | 719 | 1,331 | 3,595 | 6,655 | 7,909 | 39,545 | 86,999 | 434,995 | 956,989 | 4,784,945 |
| -1 | -5 | -11 | -55 | -121 | -605 | -719 | -1,331 | -3,595 | -6,655 | -7,909 | -39,545 | -86,999 | -434,995 | -956,989 | -4,784,945 |
