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 50,556,623, 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 | 50,556,623 | |
| -1 | -50,556,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,556,623.
Example:
1 x 50,556,623 = 50,556,623
and
-1 x -50,556,623 = 50,556,623
Notice both answers equal 50,556,623
With that explanation out of the way, let's continue. Next, we take the number 50,556,623 and divide it by 2:
50,556,623 ÷ 2 = 25,278,311.5
If the quotient is a whole number, then 2 and 25,278,311.5 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 | 50,556,623 | |
| -1 | -50,556,623 |
Now, we try dividing 50,556,623 by 3:
50,556,623 ÷ 3 = 16,852,207.6667
If the quotient is a whole number, then 3 and 16,852,207.6667 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 | 50,556,623 | |
| -1 | -50,556,623 |
Let's try dividing by 4:
50,556,623 ÷ 4 = 12,639,155.75
If the quotient is a whole number, then 4 and 12,639,155.75 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 | 50,556,623 | |
| -1 | 50,556,623 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 103 | 221 | 1,339 | 1,751 | 2,221 | 22,763 | 28,873 | 37,757 | 228,763 | 490,841 | 2,973,919 | 3,888,971 | 50,556,623 |
| -1 | -13 | -17 | -103 | -221 | -1,339 | -1,751 | -2,221 | -22,763 | -28,873 | -37,757 | -228,763 | -490,841 | -2,973,919 | -3,888,971 | -50,556,623 |
