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 50,675,147, 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 | 50,675,147 | |
| -1 | -50,675,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,675,147.
Example:
1 x 50,675,147 = 50,675,147
and
-1 x -50,675,147 = 50,675,147
Notice both answers equal 50,675,147
With that explanation out of the way, let's continue. Next, we take the number 50,675,147 and divide it by 2:
50,675,147 ÷ 2 = 25,337,573.5
If the quotient is a whole number, then 2 and 25,337,573.5 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 | 50,675,147 | |
| -1 | -50,675,147 |
Now, we try dividing 50,675,147 by 3:
50,675,147 ÷ 3 = 16,891,715.6667
If the quotient is a whole number, then 3 and 16,891,715.6667 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 | 50,675,147 | |
| -1 | -50,675,147 |
Let's try dividing by 4:
50,675,147 ÷ 4 = 12,668,786.75
If the quotient is a whole number, then 4 and 12,668,786.75 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 | 50,675,147 | |
| -1 | 50,675,147 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 151 | 323 | 1,039 | 2,567 | 2,869 | 17,663 | 19,741 | 48,773 | 156,889 | 335,597 | 2,667,113 | 2,980,891 | 50,675,147 |
| -1 | -17 | -19 | -151 | -323 | -1,039 | -2,567 | -2,869 | -17,663 | -19,741 | -48,773 | -156,889 | -335,597 | -2,667,113 | -2,980,891 | -50,675,147 |
