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 122,103,043, 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 | 122,103,043 | |
| -1 | -122,103,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,103,043.
Example:
1 x 122,103,043 = 122,103,043
and
-1 x -122,103,043 = 122,103,043
Notice both answers equal 122,103,043
With that explanation out of the way, let's continue. Next, we take the number 122,103,043 and divide it by 2:
122,103,043 ÷ 2 = 61,051,521.5
If the quotient is a whole number, then 2 and 61,051,521.5 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 | 122,103,043 | |
| -1 | -122,103,043 |
Now, we try dividing 122,103,043 by 3:
122,103,043 ÷ 3 = 40,701,014.3333
If the quotient is a whole number, then 3 and 40,701,014.3333 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 | 122,103,043 | |
| -1 | -122,103,043 |
Let's try dividing by 4:
122,103,043 ÷ 4 = 30,525,760.75
If the quotient is a whole number, then 4 and 30,525,760.75 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 | 122,103,043 | |
| -1 | 122,103,043 |
If you did it right, you will end up with this table:
| 1 | 41 | 53 | 83 | 677 | 2,173 | 3,403 | 4,399 | 27,757 | 35,881 | 56,191 | 180,359 | 1,471,121 | 2,303,831 | 2,978,123 | 122,103,043 |
| -1 | -41 | -53 | -83 | -677 | -2,173 | -3,403 | -4,399 | -27,757 | -35,881 | -56,191 | -180,359 | -1,471,121 | -2,303,831 | -2,978,123 | -122,103,043 |
