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 50,165,615, 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 | 50,165,615 | |
| -1 | -50,165,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,165,615.
Example:
1 x 50,165,615 = 50,165,615
and
-1 x -50,165,615 = 50,165,615
Notice both answers equal 50,165,615
With that explanation out of the way, let's continue. Next, we take the number 50,165,615 and divide it by 2:
50,165,615 ÷ 2 = 25,082,807.5
If the quotient is a whole number, then 2 and 25,082,807.5 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 | 50,165,615 | |
| -1 | -50,165,615 |
Now, we try dividing 50,165,615 by 3:
50,165,615 ÷ 3 = 16,721,871.6667
If the quotient is a whole number, then 3 and 16,721,871.6667 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 | 50,165,615 | |
| -1 | -50,165,615 |
Let's try dividing by 4:
50,165,615 ÷ 4 = 12,541,403.75
If the quotient is a whole number, then 4 and 12,541,403.75 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 | 50,165,615 | |
| -1 | 50,165,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 109 | 415 | 545 | 1,109 | 5,545 | 9,047 | 45,235 | 92,047 | 120,881 | 460,235 | 604,405 | 10,033,123 | 50,165,615 |
| -1 | -5 | -83 | -109 | -415 | -545 | -1,109 | -5,545 | -9,047 | -45,235 | -92,047 | -120,881 | -460,235 | -604,405 | -10,033,123 | -50,165,615 |
