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 50,225,785, 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 | 50,225,785 | |
| -1 | -50,225,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,225,785.
Example:
1 x 50,225,785 = 50,225,785
and
-1 x -50,225,785 = 50,225,785
Notice both answers equal 50,225,785
With that explanation out of the way, let's continue. Next, we take the number 50,225,785 and divide it by 2:
50,225,785 ÷ 2 = 25,112,892.5
If the quotient is a whole number, then 2 and 25,112,892.5 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 | 50,225,785 | |
| -1 | -50,225,785 |
Now, we try dividing 50,225,785 by 3:
50,225,785 ÷ 3 = 16,741,928.3333
If the quotient is a whole number, then 3 and 16,741,928.3333 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 | 50,225,785 | |
| -1 | -50,225,785 |
Let's try dividing by 4:
50,225,785 ÷ 4 = 12,556,446.25
If the quotient is a whole number, then 4 and 12,556,446.25 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 | 50,225,785 | |
| -1 | 50,225,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 271 | 367 | 505 | 1,355 | 1,835 | 27,371 | 37,067 | 99,457 | 136,855 | 185,335 | 497,285 | 10,045,157 | 50,225,785 |
| -1 | -5 | -101 | -271 | -367 | -505 | -1,355 | -1,835 | -27,371 | -37,067 | -99,457 | -136,855 | -185,335 | -497,285 | -10,045,157 | -50,225,785 |
