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 50,150,555, 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 | 50,150,555 | |
| -1 | -50,150,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,150,555.
Example:
1 x 50,150,555 = 50,150,555
and
-1 x -50,150,555 = 50,150,555
Notice both answers equal 50,150,555
With that explanation out of the way, let's continue. Next, we take the number 50,150,555 and divide it by 2:
50,150,555 ÷ 2 = 25,075,277.5
If the quotient is a whole number, then 2 and 25,075,277.5 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 | 50,150,555 | |
| -1 | -50,150,555 |
Now, we try dividing 50,150,555 by 3:
50,150,555 ÷ 3 = 16,716,851.6667
If the quotient is a whole number, then 3 and 16,716,851.6667 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 | 50,150,555 | |
| -1 | -50,150,555 |
Let's try dividing by 4:
50,150,555 ÷ 4 = 12,537,638.75
If the quotient is a whole number, then 4 and 12,537,638.75 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 | 50,150,555 | |
| -1 | 50,150,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 110,221 | 551,105 | 771,547 | 1,432,873 | 3,857,735 | 7,164,365 | 10,030,111 | 50,150,555 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -110,221 | -551,105 | -771,547 | -1,432,873 | -3,857,735 | -7,164,365 | -10,030,111 | -50,150,555 |
