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 42,003,103, 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 | 42,003,103 | |
| -1 | -42,003,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,003,103.
Example:
1 x 42,003,103 = 42,003,103
and
-1 x -42,003,103 = 42,003,103
Notice both answers equal 42,003,103
With that explanation out of the way, let's continue. Next, we take the number 42,003,103 and divide it by 2:
42,003,103 ÷ 2 = 21,001,551.5
If the quotient is a whole number, then 2 and 21,001,551.5 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 | 42,003,103 | |
| -1 | -42,003,103 |
Now, we try dividing 42,003,103 by 3:
42,003,103 ÷ 3 = 14,001,034.3333
If the quotient is a whole number, then 3 and 14,001,034.3333 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 | 42,003,103 | |
| -1 | -42,003,103 |
Let's try dividing by 4:
42,003,103 ÷ 4 = 10,500,775.75
If the quotient is a whole number, then 4 and 10,500,775.75 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 | 42,003,103 | |
| -1 | 42,003,103 |
If you did it right, you will end up with this table:
| 1 | 37 | 59 | 71 | 271 | 2,183 | 2,627 | 4,189 | 10,027 | 15,989 | 19,241 | 154,993 | 591,593 | 711,917 | 1,135,219 | 42,003,103 |
| -1 | -37 | -59 | -71 | -271 | -2,183 | -2,627 | -4,189 | -10,027 | -15,989 | -19,241 | -154,993 | -591,593 | -711,917 | -1,135,219 | -42,003,103 |
