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 50,615,653, 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 | 50,615,653 | |
| -1 | -50,615,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,615,653.
Example:
1 x 50,615,653 = 50,615,653
and
-1 x -50,615,653 = 50,615,653
Notice both answers equal 50,615,653
With that explanation out of the way, let's continue. Next, we take the number 50,615,653 and divide it by 2:
50,615,653 ÷ 2 = 25,307,826.5
If the quotient is a whole number, then 2 and 25,307,826.5 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 | 50,615,653 | |
| -1 | -50,615,653 |
Now, we try dividing 50,615,653 by 3:
50,615,653 ÷ 3 = 16,871,884.3333
If the quotient is a whole number, then 3 and 16,871,884.3333 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 | 50,615,653 | |
| -1 | -50,615,653 |
Let's try dividing by 4:
50,615,653 ÷ 4 = 12,653,913.25
If the quotient is a whole number, then 4 and 12,653,913.25 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 | 50,615,653 | |
| -1 | 50,615,653 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 151 | 341 | 983 | 1,661 | 4,681 | 10,813 | 30,473 | 51,491 | 148,433 | 335,203 | 1,632,763 | 4,601,423 | 50,615,653 |
| -1 | -11 | -31 | -151 | -341 | -983 | -1,661 | -4,681 | -10,813 | -30,473 | -51,491 | -148,433 | -335,203 | -1,632,763 | -4,601,423 | -50,615,653 |
