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 50,289,451, 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 | 50,289,451 | |
| -1 | -50,289,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,289,451.
Example:
1 x 50,289,451 = 50,289,451
and
-1 x -50,289,451 = 50,289,451
Notice both answers equal 50,289,451
With that explanation out of the way, let's continue. Next, we take the number 50,289,451 and divide it by 2:
50,289,451 ÷ 2 = 25,144,725.5
If the quotient is a whole number, then 2 and 25,144,725.5 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 | 50,289,451 | |
| -1 | -50,289,451 |
Now, we try dividing 50,289,451 by 3:
50,289,451 ÷ 3 = 16,763,150.3333
If the quotient is a whole number, then 3 and 16,763,150.3333 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 | 50,289,451 | |
| -1 | -50,289,451 |
Let's try dividing by 4:
50,289,451 ÷ 4 = 12,572,362.75
If the quotient is a whole number, then 4 and 12,572,362.75 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 | 50,289,451 | |
| -1 | 50,289,451 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 83 | 493 | 1,229 | 1,411 | 2,407 | 20,893 | 35,641 | 40,919 | 102,007 | 605,897 | 1,734,119 | 2,958,203 | 50,289,451 |
| -1 | -17 | -29 | -83 | -493 | -1,229 | -1,411 | -2,407 | -20,893 | -35,641 | -40,919 | -102,007 | -605,897 | -1,734,119 | -2,958,203 | -50,289,451 |
