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 49,206,648, 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 | 49,206,648 | |
| -1 | -49,206,648 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,206,648.
Example:
1 x 49,206,648 = 49,206,648
and
-1 x -49,206,648 = 49,206,648
Notice both answers equal 49,206,648
With that explanation out of the way, let's continue. Next, we take the number 49,206,648 and divide it by 2:
49,206,648 ÷ 2 = 24,603,324
If the quotient is a whole number, then 2 and 24,603,324 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 24,603,324 | 49,206,648 | |
| -1 | -2 | -24,603,324 | -49,206,648 |
Now, we try dividing 49,206,648 by 3:
49,206,648 ÷ 3 = 16,402,216
If the quotient is a whole number, then 3 and 16,402,216 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 16,402,216 | 24,603,324 | 49,206,648 | |
| -1 | -2 | -3 | -16,402,216 | -24,603,324 | -49,206,648 |
Let's try dividing by 4:
49,206,648 ÷ 4 = 12,301,662
If the quotient is a whole number, then 4 and 12,301,662 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 12,301,662 | 16,402,216 | 24,603,324 | 49,206,648 | |
| -1 | -2 | -3 | -4 | -12,301,662 | -16,402,216 | -24,603,324 | 49,206,648 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 8 | 12 | 24 | 2,050,277 | 4,100,554 | 6,150,831 | 8,201,108 | 12,301,662 | 16,402,216 | 24,603,324 | 49,206,648 |
| -1 | -2 | -3 | -4 | -6 | -8 | -12 | -24 | -2,050,277 | -4,100,554 | -6,150,831 | -8,201,108 | -12,301,662 | -16,402,216 | -24,603,324 | -49,206,648 |
