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 4,905,439, 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 | 4,905,439 | |
| -1 | -4,905,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,905,439.
Example:
1 x 4,905,439 = 4,905,439
and
-1 x -4,905,439 = 4,905,439
Notice both answers equal 4,905,439
With that explanation out of the way, let's continue. Next, we take the number 4,905,439 and divide it by 2:
4,905,439 ÷ 2 = 2,452,719.5
If the quotient is a whole number, then 2 and 2,452,719.5 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 | 4,905,439 | |
| -1 | -4,905,439 |
Now, we try dividing 4,905,439 by 3:
4,905,439 ÷ 3 = 1,635,146.3333
If the quotient is a whole number, then 3 and 1,635,146.3333 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 | 4,905,439 | |
| -1 | -4,905,439 |
Let's try dividing by 4:
4,905,439 ÷ 4 = 1,226,359.75
If the quotient is a whole number, then 4 and 1,226,359.75 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 | 4,905,439 | |
| -1 | 4,905,439 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 49 | 77 | 133 | 209 | 479 | 539 | 931 | 1,463 | 3,353 | 5,269 | 9,101 | 10,241 | 23,471 | 36,883 | 63,707 | 100,111 | 258,181 | 445,949 | 700,777 | 4,905,439 |
| -1 | -7 | -11 | -19 | -49 | -77 | -133 | -209 | -479 | -539 | -931 | -1,463 | -3,353 | -5,269 | -9,101 | -10,241 | -23,471 | -36,883 | -63,707 | -100,111 | -258,181 | -445,949 | -700,777 | -4,905,439 |
