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 50,164,265, 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 | 50,164,265 | |
| -1 | -50,164,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,164,265.
Example:
1 x 50,164,265 = 50,164,265
and
-1 x -50,164,265 = 50,164,265
Notice both answers equal 50,164,265
With that explanation out of the way, let's continue. Next, we take the number 50,164,265 and divide it by 2:
50,164,265 ÷ 2 = 25,082,132.5
If the quotient is a whole number, then 2 and 25,082,132.5 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 | 50,164,265 | |
| -1 | -50,164,265 |
Now, we try dividing 50,164,265 by 3:
50,164,265 ÷ 3 = 16,721,421.6667
If the quotient is a whole number, then 3 and 16,721,421.6667 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 | 50,164,265 | |
| -1 | -50,164,265 |
Let's try dividing by 4:
50,164,265 ÷ 4 = 12,541,066.25
If the quotient is a whole number, then 4 and 12,541,066.25 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 | 50,164,265 | |
| -1 | 50,164,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 61 | 115 | 305 | 1,403 | 7,015 | 7,151 | 35,755 | 164,473 | 436,211 | 822,365 | 2,181,055 | 10,032,853 | 50,164,265 |
| -1 | -5 | -23 | -61 | -115 | -305 | -1,403 | -7,015 | -7,151 | -35,755 | -164,473 | -436,211 | -822,365 | -2,181,055 | -10,032,853 | -50,164,265 |
