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 50,175,185, 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 | 50,175,185 | |
| -1 | -50,175,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,175,185.
Example:
1 x 50,175,185 = 50,175,185
and
-1 x -50,175,185 = 50,175,185
Notice both answers equal 50,175,185
With that explanation out of the way, let's continue. Next, we take the number 50,175,185 and divide it by 2:
50,175,185 ÷ 2 = 25,087,592.5
If the quotient is a whole number, then 2 and 25,087,592.5 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 | 50,175,185 | |
| -1 | -50,175,185 |
Now, we try dividing 50,175,185 by 3:
50,175,185 ÷ 3 = 16,725,061.6667
If the quotient is a whole number, then 3 and 16,725,061.6667 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 | 50,175,185 | |
| -1 | -50,175,185 |
Let's try dividing by 4:
50,175,185 ÷ 4 = 12,543,796.25
If the quotient is a whole number, then 4 and 12,543,796.25 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 | 50,175,185 | |
| -1 | 50,175,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 311 | 787 | 1,555 | 3,935 | 12,751 | 32,267 | 63,755 | 161,335 | 244,757 | 1,223,785 | 10,035,037 | 50,175,185 |
| -1 | -5 | -41 | -205 | -311 | -787 | -1,555 | -3,935 | -12,751 | -32,267 | -63,755 | -161,335 | -244,757 | -1,223,785 | -10,035,037 | -50,175,185 |
