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 4,782,239, 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 | 4,782,239 | |
| -1 | -4,782,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,782,239.
Example:
1 x 4,782,239 = 4,782,239
and
-1 x -4,782,239 = 4,782,239
Notice both answers equal 4,782,239
With that explanation out of the way, let's continue. Next, we take the number 4,782,239 and divide it by 2:
4,782,239 ÷ 2 = 2,391,119.5
If the quotient is a whole number, then 2 and 2,391,119.5 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 | 4,782,239 | |
| -1 | -4,782,239 |
Now, we try dividing 4,782,239 by 3:
4,782,239 ÷ 3 = 1,594,079.6667
If the quotient is a whole number, then 3 and 1,594,079.6667 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 | 4,782,239 | |
| -1 | -4,782,239 |
Let's try dividing by 4:
4,782,239 ÷ 4 = 1,195,559.75
If the quotient is a whole number, then 4 and 1,195,559.75 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 | 4,782,239 | |
| -1 | 4,782,239 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 173 | 359 | 1,211 | 1,903 | 2,513 | 3,949 | 13,321 | 27,643 | 62,107 | 434,749 | 683,177 | 4,782,239 |
| -1 | -7 | -11 | -77 | -173 | -359 | -1,211 | -1,903 | -2,513 | -3,949 | -13,321 | -27,643 | -62,107 | -434,749 | -683,177 | -4,782,239 |
