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 50,316,155, 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 | 50,316,155 | |
| -1 | -50,316,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,316,155.
Example:
1 x 50,316,155 = 50,316,155
and
-1 x -50,316,155 = 50,316,155
Notice both answers equal 50,316,155
With that explanation out of the way, let's continue. Next, we take the number 50,316,155 and divide it by 2:
50,316,155 ÷ 2 = 25,158,077.5
If the quotient is a whole number, then 2 and 25,158,077.5 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 | 50,316,155 | |
| -1 | -50,316,155 |
Now, we try dividing 50,316,155 by 3:
50,316,155 ÷ 3 = 16,772,051.6667
If the quotient is a whole number, then 3 and 16,772,051.6667 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 | 50,316,155 | |
| -1 | -50,316,155 |
Let's try dividing by 4:
50,316,155 ÷ 4 = 12,579,038.75
If the quotient is a whole number, then 4 and 12,579,038.75 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 | 50,316,155 | |
| -1 | 50,316,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 199 | 305 | 829 | 995 | 4,145 | 12,139 | 50,569 | 60,695 | 164,971 | 252,845 | 824,855 | 10,063,231 | 50,316,155 |
| -1 | -5 | -61 | -199 | -305 | -829 | -995 | -4,145 | -12,139 | -50,569 | -60,695 | -164,971 | -252,845 | -824,855 | -10,063,231 | -50,316,155 |
