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 50,842,673, 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 | 50,842,673 | |
| -1 | -50,842,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,842,673.
Example:
1 x 50,842,673 = 50,842,673
and
-1 x -50,842,673 = 50,842,673
Notice both answers equal 50,842,673
With that explanation out of the way, let's continue. Next, we take the number 50,842,673 and divide it by 2:
50,842,673 ÷ 2 = 25,421,336.5
If the quotient is a whole number, then 2 and 25,421,336.5 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 | 50,842,673 | |
| -1 | -50,842,673 |
Now, we try dividing 50,842,673 by 3:
50,842,673 ÷ 3 = 16,947,557.6667
If the quotient is a whole number, then 3 and 16,947,557.6667 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 | 50,842,673 | |
| -1 | -50,842,673 |
Let's try dividing by 4:
50,842,673 ÷ 4 = 12,710,668.25
If the quotient is a whole number, then 4 and 12,710,668.25 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 | 50,842,673 | |
| -1 | 50,842,673 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 47 | 161 | 329 | 1,081 | 6,719 | 7,567 | 47,033 | 154,537 | 315,793 | 1,081,759 | 2,210,551 | 7,263,239 | 50,842,673 |
| -1 | -7 | -23 | -47 | -161 | -329 | -1,081 | -6,719 | -7,567 | -47,033 | -154,537 | -315,793 | -1,081,759 | -2,210,551 | -7,263,239 | -50,842,673 |
