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 50,170,043, 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 | 50,170,043 | |
| -1 | -50,170,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,170,043.
Example:
1 x 50,170,043 = 50,170,043
and
-1 x -50,170,043 = 50,170,043
Notice both answers equal 50,170,043
With that explanation out of the way, let's continue. Next, we take the number 50,170,043 and divide it by 2:
50,170,043 ÷ 2 = 25,085,021.5
If the quotient is a whole number, then 2 and 25,085,021.5 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 | 50,170,043 | |
| -1 | -50,170,043 |
Now, we try dividing 50,170,043 by 3:
50,170,043 ÷ 3 = 16,723,347.6667
If the quotient is a whole number, then 3 and 16,723,347.6667 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 | 50,170,043 | |
| -1 | -50,170,043 |
Let's try dividing by 4:
50,170,043 ÷ 4 = 12,542,510.75
If the quotient is a whole number, then 4 and 12,542,510.75 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 | 50,170,043 | |
| -1 | 50,170,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 38,327 | 268,289 | 421,597 | 651,559 | 2,951,179 | 4,560,913 | 7,167,149 | 50,170,043 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -38,327 | -268,289 | -421,597 | -651,559 | -2,951,179 | -4,560,913 | -7,167,149 | -50,170,043 |
