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 50,421,833, 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 | 50,421,833 | |
| -1 | -50,421,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,421,833.
Example:
1 x 50,421,833 = 50,421,833
and
-1 x -50,421,833 = 50,421,833
Notice both answers equal 50,421,833
With that explanation out of the way, let's continue. Next, we take the number 50,421,833 and divide it by 2:
50,421,833 ÷ 2 = 25,210,916.5
If the quotient is a whole number, then 2 and 25,210,916.5 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 | 50,421,833 | |
| -1 | -50,421,833 |
Now, we try dividing 50,421,833 by 3:
50,421,833 ÷ 3 = 16,807,277.6667
If the quotient is a whole number, then 3 and 16,807,277.6667 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 | 50,421,833 | |
| -1 | -50,421,833 |
Let's try dividing by 4:
50,421,833 ÷ 4 = 12,605,458.25
If the quotient is a whole number, then 4 and 12,605,458.25 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 | 50,421,833 | |
| -1 | 50,421,833 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 139 | 539 | 673 | 973 | 1,529 | 4,711 | 6,811 | 7,403 | 10,703 | 32,977 | 51,821 | 74,921 | 93,547 | 362,747 | 654,829 | 1,029,017 | 4,583,803 | 7,203,119 | 50,421,833 |
| -1 | -7 | -11 | -49 | -77 | -139 | -539 | -673 | -973 | -1,529 | -4,711 | -6,811 | -7,403 | -10,703 | -32,977 | -51,821 | -74,921 | -93,547 | -362,747 | -654,829 | -1,029,017 | -4,583,803 | -7,203,119 | -50,421,833 |
