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 40,203,011, 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 | 40,203,011 | |
| -1 | -40,203,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,203,011.
Example:
1 x 40,203,011 = 40,203,011
and
-1 x -40,203,011 = 40,203,011
Notice both answers equal 40,203,011
With that explanation out of the way, let's continue. Next, we take the number 40,203,011 and divide it by 2:
40,203,011 ÷ 2 = 20,101,505.5
If the quotient is a whole number, then 2 and 20,101,505.5 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 | 40,203,011 | |
| -1 | -40,203,011 |
Now, we try dividing 40,203,011 by 3:
40,203,011 ÷ 3 = 13,401,003.6667
If the quotient is a whole number, then 3 and 13,401,003.6667 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 | 40,203,011 | |
| -1 | -40,203,011 |
Let's try dividing by 4:
40,203,011 ÷ 4 = 10,050,752.75
If the quotient is a whole number, then 4 and 10,050,752.75 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 | 40,203,011 | |
| -1 | 40,203,011 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 229 | 391 | 449 | 3,893 | 5,267 | 7,633 | 10,327 | 89,539 | 102,821 | 175,559 | 1,747,957 | 2,364,883 | 40,203,011 |
| -1 | -17 | -23 | -229 | -391 | -449 | -3,893 | -5,267 | -7,633 | -10,327 | -89,539 | -102,821 | -175,559 | -1,747,957 | -2,364,883 | -40,203,011 |
