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 50,901,565, 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 | 50,901,565 | |
| -1 | -50,901,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,901,565.
Example:
1 x 50,901,565 = 50,901,565
and
-1 x -50,901,565 = 50,901,565
Notice both answers equal 50,901,565
With that explanation out of the way, let's continue. Next, we take the number 50,901,565 and divide it by 2:
50,901,565 ÷ 2 = 25,450,782.5
If the quotient is a whole number, then 2 and 25,450,782.5 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 | 50,901,565 | |
| -1 | -50,901,565 |
Now, we try dividing 50,901,565 by 3:
50,901,565 ÷ 3 = 16,967,188.3333
If the quotient is a whole number, then 3 and 16,967,188.3333 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 | 50,901,565 | |
| -1 | -50,901,565 |
Let's try dividing by 4:
50,901,565 ÷ 4 = 12,725,391.25
If the quotient is a whole number, then 4 and 12,725,391.25 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 | 50,901,565 | |
| -1 | 50,901,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 71,191 | 355,955 | 783,101 | 925,483 | 3,915,505 | 4,627,415 | 10,180,313 | 50,901,565 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -71,191 | -355,955 | -783,101 | -925,483 | -3,915,505 | -4,627,415 | -10,180,313 | -50,901,565 |
