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 50,152,427, 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 | 50,152,427 | |
| -1 | -50,152,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,152,427.
Example:
1 x 50,152,427 = 50,152,427
and
-1 x -50,152,427 = 50,152,427
Notice both answers equal 50,152,427
With that explanation out of the way, let's continue. Next, we take the number 50,152,427 and divide it by 2:
50,152,427 ÷ 2 = 25,076,213.5
If the quotient is a whole number, then 2 and 25,076,213.5 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 | 50,152,427 | |
| -1 | -50,152,427 |
Now, we try dividing 50,152,427 by 3:
50,152,427 ÷ 3 = 16,717,475.6667
If the quotient is a whole number, then 3 and 16,717,475.6667 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 | 50,152,427 | |
| -1 | -50,152,427 |
Let's try dividing by 4:
50,152,427 ÷ 4 = 12,538,106.75
If the quotient is a whole number, then 4 and 12,538,106.75 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 | 50,152,427 | |
| -1 | 50,152,427 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 127 | 481 | 821 | 1,651 | 4,699 | 10,673 | 30,377 | 61,087 | 104,267 | 394,901 | 1,355,471 | 3,857,879 | 50,152,427 |
| -1 | -13 | -37 | -127 | -481 | -821 | -1,651 | -4,699 | -10,673 | -30,377 | -61,087 | -104,267 | -394,901 | -1,355,471 | -3,857,879 | -50,152,427 |
