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 20,003,011, 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 | 20,003,011 | |
| -1 | -20,003,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,003,011.
Example:
1 x 20,003,011 = 20,003,011
and
-1 x -20,003,011 = 20,003,011
Notice both answers equal 20,003,011
With that explanation out of the way, let's continue. Next, we take the number 20,003,011 and divide it by 2:
20,003,011 ÷ 2 = 10,001,505.5
If the quotient is a whole number, then 2 and 10,001,505.5 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 | 20,003,011 | |
| -1 | -20,003,011 |
Now, we try dividing 20,003,011 by 3:
20,003,011 ÷ 3 = 6,667,670.3333
If the quotient is a whole number, then 3 and 6,667,670.3333 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 | 20,003,011 | |
| -1 | -20,003,011 |
Let's try dividing by 4:
20,003,011 ÷ 4 = 5,000,752.75
If the quotient is a whole number, then 4 and 5,000,752.75 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 | 20,003,011 | |
| -1 | 20,003,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 211 | 467 | 1,477 | 3,269 | 6,119 | 13,543 | 42,833 | 94,801 | 98,537 | 689,759 | 2,857,573 | 20,003,011 |
| -1 | -7 | -29 | -203 | -211 | -467 | -1,477 | -3,269 | -6,119 | -13,543 | -42,833 | -94,801 | -98,537 | -689,759 | -2,857,573 | -20,003,011 |
