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 50,377,387, 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 | 50,377,387 | |
| -1 | -50,377,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,377,387.
Example:
1 x 50,377,387 = 50,377,387
and
-1 x -50,377,387 = 50,377,387
Notice both answers equal 50,377,387
With that explanation out of the way, let's continue. Next, we take the number 50,377,387 and divide it by 2:
50,377,387 ÷ 2 = 25,188,693.5
If the quotient is a whole number, then 2 and 25,188,693.5 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 | 50,377,387 | |
| -1 | -50,377,387 |
Now, we try dividing 50,377,387 by 3:
50,377,387 ÷ 3 = 16,792,462.3333
If the quotient is a whole number, then 3 and 16,792,462.3333 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 | 50,377,387 | |
| -1 | -50,377,387 |
Let's try dividing by 4:
50,377,387 ÷ 4 = 12,594,346.75
If the quotient is a whole number, then 4 and 12,594,346.75 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 | 50,377,387 | |
| -1 | 50,377,387 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 167 | 263 | 1,147 | 5,177 | 6,179 | 8,153 | 9,731 | 43,921 | 191,549 | 301,661 | 1,361,551 | 1,625,077 | 50,377,387 |
| -1 | -31 | -37 | -167 | -263 | -1,147 | -5,177 | -6,179 | -8,153 | -9,731 | -43,921 | -191,549 | -301,661 | -1,361,551 | -1,625,077 | -50,377,387 |
