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 50,221,105, 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 | 50,221,105 | |
| -1 | -50,221,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,221,105.
Example:
1 x 50,221,105 = 50,221,105
and
-1 x -50,221,105 = 50,221,105
Notice both answers equal 50,221,105
With that explanation out of the way, let's continue. Next, we take the number 50,221,105 and divide it by 2:
50,221,105 ÷ 2 = 25,110,552.5
If the quotient is a whole number, then 2 and 25,110,552.5 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 | 50,221,105 | |
| -1 | -50,221,105 |
Now, we try dividing 50,221,105 by 3:
50,221,105 ÷ 3 = 16,740,368.3333
If the quotient is a whole number, then 3 and 16,740,368.3333 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 | 50,221,105 | |
| -1 | -50,221,105 |
Let's try dividing by 4:
50,221,105 ÷ 4 = 12,555,276.25
If the quotient is a whole number, then 4 and 12,555,276.25 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 | 50,221,105 | |
| -1 | 50,221,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 22,271 | 111,355 | 244,981 | 913,111 | 1,224,905 | 4,565,555 | 10,044,221 | 50,221,105 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -22,271 | -111,355 | -244,981 | -913,111 | -1,224,905 | -4,565,555 | -10,044,221 | -50,221,105 |
