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 50,830,507, 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 | 50,830,507 | |
| -1 | -50,830,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,830,507.
Example:
1 x 50,830,507 = 50,830,507
and
-1 x -50,830,507 = 50,830,507
Notice both answers equal 50,830,507
With that explanation out of the way, let's continue. Next, we take the number 50,830,507 and divide it by 2:
50,830,507 ÷ 2 = 25,415,253.5
If the quotient is a whole number, then 2 and 25,415,253.5 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 | 50,830,507 | |
| -1 | -50,830,507 |
Now, we try dividing 50,830,507 by 3:
50,830,507 ÷ 3 = 16,943,502.3333
If the quotient is a whole number, then 3 and 16,943,502.3333 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 | 50,830,507 | |
| -1 | -50,830,507 |
Let's try dividing by 4:
50,830,507 ÷ 4 = 12,707,626.75
If the quotient is a whole number, then 4 and 12,707,626.75 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 | 50,830,507 | |
| -1 | 50,830,507 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 61 | 91 | 427 | 793 | 5,551 | 9,157 | 64,099 | 119,041 | 558,577 | 833,287 | 3,910,039 | 7,261,501 | 50,830,507 |
| -1 | -7 | -13 | -61 | -91 | -427 | -793 | -5,551 | -9,157 | -64,099 | -119,041 | -558,577 | -833,287 | -3,910,039 | -7,261,501 | -50,830,507 |
