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 50,122,541, 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 | 50,122,541 | |
| -1 | -50,122,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,122,541.
Example:
1 x 50,122,541 = 50,122,541
and
-1 x -50,122,541 = 50,122,541
Notice both answers equal 50,122,541
With that explanation out of the way, let's continue. Next, we take the number 50,122,541 and divide it by 2:
50,122,541 ÷ 2 = 25,061,270.5
If the quotient is a whole number, then 2 and 25,061,270.5 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 | 50,122,541 | |
| -1 | -50,122,541 |
Now, we try dividing 50,122,541 by 3:
50,122,541 ÷ 3 = 16,707,513.6667
If the quotient is a whole number, then 3 and 16,707,513.6667 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 | 50,122,541 | |
| -1 | -50,122,541 |
Let's try dividing by 4:
50,122,541 ÷ 4 = 12,530,635.25
If the quotient is a whole number, then 4 and 12,530,635.25 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 | 50,122,541 | |
| -1 | 50,122,541 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 49 | 61 | 287 | 409 | 427 | 2,009 | 2,501 | 2,863 | 2,989 | 16,769 | 17,507 | 20,041 | 24,949 | 117,383 | 122,549 | 174,643 | 821,681 | 1,022,909 | 1,222,501 | 7,160,363 | 50,122,541 |
| -1 | -7 | -41 | -49 | -61 | -287 | -409 | -427 | -2,009 | -2,501 | -2,863 | -2,989 | -16,769 | -17,507 | -20,041 | -24,949 | -117,383 | -122,549 | -174,643 | -821,681 | -1,022,909 | -1,222,501 | -7,160,363 | -50,122,541 |
