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 45,003,811, 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 | 45,003,811 | |
| -1 | -45,003,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,003,811.
Example:
1 x 45,003,811 = 45,003,811
and
-1 x -45,003,811 = 45,003,811
Notice both answers equal 45,003,811
With that explanation out of the way, let's continue. Next, we take the number 45,003,811 and divide it by 2:
45,003,811 ÷ 2 = 22,501,905.5
If the quotient is a whole number, then 2 and 22,501,905.5 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 | 45,003,811 | |
| -1 | -45,003,811 |
Now, we try dividing 45,003,811 by 3:
45,003,811 ÷ 3 = 15,001,270.3333
If the quotient is a whole number, then 3 and 15,001,270.3333 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 | 45,003,811 | |
| -1 | -45,003,811 |
Let's try dividing by 4:
45,003,811 ÷ 4 = 11,250,952.75
If the quotient is a whole number, then 4 and 11,250,952.75 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 | 45,003,811 | |
| -1 | 45,003,811 |
If you did it right, you will end up with this table:
| 1 | 17 | 109 | 149 | 163 | 1,853 | 2,533 | 2,771 | 16,241 | 17,767 | 24,287 | 276,097 | 302,039 | 412,879 | 2,647,283 | 45,003,811 |
| -1 | -17 | -109 | -149 | -163 | -1,853 | -2,533 | -2,771 | -16,241 | -17,767 | -24,287 | -276,097 | -302,039 | -412,879 | -2,647,283 | -45,003,811 |
