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 50,465,261, 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 | 50,465,261 | |
| -1 | -50,465,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,465,261.
Example:
1 x 50,465,261 = 50,465,261
and
-1 x -50,465,261 = 50,465,261
Notice both answers equal 50,465,261
With that explanation out of the way, let's continue. Next, we take the number 50,465,261 and divide it by 2:
50,465,261 ÷ 2 = 25,232,630.5
If the quotient is a whole number, then 2 and 25,232,630.5 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 | 50,465,261 | |
| -1 | -50,465,261 |
Now, we try dividing 50,465,261 by 3:
50,465,261 ÷ 3 = 16,821,753.6667
If the quotient is a whole number, then 3 and 16,821,753.6667 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 | 50,465,261 | |
| -1 | -50,465,261 |
Let's try dividing by 4:
50,465,261 ÷ 4 = 12,616,315.25
If the quotient is a whole number, then 4 and 12,616,315.25 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 | 50,465,261 | |
| -1 | 50,465,261 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 131 | 917 | 1,441 | 5,003 | 10,087 | 35,021 | 55,033 | 385,231 | 655,393 | 4,587,751 | 7,209,323 | 50,465,261 |
| -1 | -7 | -11 | -77 | -131 | -917 | -1,441 | -5,003 | -10,087 | -35,021 | -55,033 | -385,231 | -655,393 | -4,587,751 | -7,209,323 | -50,465,261 |
