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 4,780,349, 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 | 4,780,349 | |
| -1 | -4,780,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,780,349.
Example:
1 x 4,780,349 = 4,780,349
and
-1 x -4,780,349 = 4,780,349
Notice both answers equal 4,780,349
With that explanation out of the way, let's continue. Next, we take the number 4,780,349 and divide it by 2:
4,780,349 ÷ 2 = 2,390,174.5
If the quotient is a whole number, then 2 and 2,390,174.5 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 | 4,780,349 | |
| -1 | -4,780,349 |
Now, we try dividing 4,780,349 by 3:
4,780,349 ÷ 3 = 1,593,449.6667
If the quotient is a whole number, then 3 and 1,593,449.6667 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 | 4,780,349 | |
| -1 | -4,780,349 |
Let's try dividing by 4:
4,780,349 ÷ 4 = 1,195,087.25
If the quotient is a whole number, then 4 and 1,195,087.25 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 | 4,780,349 | |
| -1 | 4,780,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 139 | 289 | 973 | 2,023 | 2,363 | 4,913 | 16,541 | 34,391 | 40,171 | 281,197 | 682,907 | 4,780,349 |
| -1 | -7 | -17 | -119 | -139 | -289 | -973 | -2,023 | -2,363 | -4,913 | -16,541 | -34,391 | -40,171 | -281,197 | -682,907 | -4,780,349 |
