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 50,213,527, 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 | 50,213,527 | |
| -1 | -50,213,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,213,527.
Example:
1 x 50,213,527 = 50,213,527
and
-1 x -50,213,527 = 50,213,527
Notice both answers equal 50,213,527
With that explanation out of the way, let's continue. Next, we take the number 50,213,527 and divide it by 2:
50,213,527 ÷ 2 = 25,106,763.5
If the quotient is a whole number, then 2 and 25,106,763.5 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 | 50,213,527 | |
| -1 | -50,213,527 |
Now, we try dividing 50,213,527 by 3:
50,213,527 ÷ 3 = 16,737,842.3333
If the quotient is a whole number, then 3 and 16,737,842.3333 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 | 50,213,527 | |
| -1 | -50,213,527 |
Let's try dividing by 4:
50,213,527 ÷ 4 = 12,553,381.75
If the quotient is a whole number, then 4 and 12,553,381.75 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 | 50,213,527 | |
| -1 | 50,213,527 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 197 | 1,379 | 2,561 | 2,801 | 17,927 | 19,607 | 36,413 | 254,891 | 551,797 | 3,862,579 | 7,173,361 | 50,213,527 |
| -1 | -7 | -13 | -91 | -197 | -1,379 | -2,561 | -2,801 | -17,927 | -19,607 | -36,413 | -254,891 | -551,797 | -3,862,579 | -7,173,361 | -50,213,527 |
