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 50,410,321, 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 | 50,410,321 | |
| -1 | -50,410,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,410,321.
Example:
1 x 50,410,321 = 50,410,321
and
-1 x -50,410,321 = 50,410,321
Notice both answers equal 50,410,321
With that explanation out of the way, let's continue. Next, we take the number 50,410,321 and divide it by 2:
50,410,321 ÷ 2 = 25,205,160.5
If the quotient is a whole number, then 2 and 25,205,160.5 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 | 50,410,321 | |
| -1 | -50,410,321 |
Now, we try dividing 50,410,321 by 3:
50,410,321 ÷ 3 = 16,803,440.3333
If the quotient is a whole number, then 3 and 16,803,440.3333 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 | 50,410,321 | |
| -1 | -50,410,321 |
Let's try dividing by 4:
50,410,321 ÷ 4 = 12,602,580.25
If the quotient is a whole number, then 4 and 12,602,580.25 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 | 50,410,321 | |
| -1 | 50,410,321 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 307 | 743 | 3,991 | 5,219 | 9,659 | 12,631 | 67,847 | 164,203 | 228,101 | 2,965,313 | 3,877,717 | 50,410,321 |
| -1 | -13 | -17 | -221 | -307 | -743 | -3,991 | -5,219 | -9,659 | -12,631 | -67,847 | -164,203 | -228,101 | -2,965,313 | -3,877,717 | -50,410,321 |
