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 50,217,055, 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 | 50,217,055 | |
| -1 | -50,217,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,217,055.
Example:
1 x 50,217,055 = 50,217,055
and
-1 x -50,217,055 = 50,217,055
Notice both answers equal 50,217,055
With that explanation out of the way, let's continue. Next, we take the number 50,217,055 and divide it by 2:
50,217,055 ÷ 2 = 25,108,527.5
If the quotient is a whole number, then 2 and 25,108,527.5 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 | 50,217,055 | |
| -1 | -50,217,055 |
Now, we try dividing 50,217,055 by 3:
50,217,055 ÷ 3 = 16,739,018.3333
If the quotient is a whole number, then 3 and 16,739,018.3333 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 | 50,217,055 | |
| -1 | -50,217,055 |
Let's try dividing by 4:
50,217,055 ÷ 4 = 12,554,263.75
If the quotient is a whole number, then 4 and 12,554,263.75 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 | 50,217,055 | |
| -1 | 50,217,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 961 | 1,085 | 1,493 | 4,805 | 6,727 | 7,465 | 10,451 | 33,635 | 46,283 | 52,255 | 231,415 | 323,981 | 1,434,773 | 1,619,905 | 7,173,865 | 10,043,411 | 50,217,055 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -961 | -1,085 | -1,493 | -4,805 | -6,727 | -7,465 | -10,451 | -33,635 | -46,283 | -52,255 | -231,415 | -323,981 | -1,434,773 | -1,619,905 | -7,173,865 | -10,043,411 | -50,217,055 |
