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 40,500,109, 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 | 40,500,109 | |
| -1 | -40,500,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,500,109.
Example:
1 x 40,500,109 = 40,500,109
and
-1 x -40,500,109 = 40,500,109
Notice both answers equal 40,500,109
With that explanation out of the way, let's continue. Next, we take the number 40,500,109 and divide it by 2:
40,500,109 ÷ 2 = 20,250,054.5
If the quotient is a whole number, then 2 and 20,250,054.5 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 | 40,500,109 | |
| -1 | -40,500,109 |
Now, we try dividing 40,500,109 by 3:
40,500,109 ÷ 3 = 13,500,036.3333
If the quotient is a whole number, then 3 and 13,500,036.3333 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 | 40,500,109 | |
| -1 | -40,500,109 |
Let's try dividing by 4:
40,500,109 ÷ 4 = 10,125,027.25
If the quotient is a whole number, then 4 and 10,125,027.25 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 | 40,500,109 | |
| -1 | 40,500,109 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 53 | 559 | 689 | 1,367 | 2,279 | 17,771 | 29,627 | 58,781 | 72,451 | 764,153 | 941,863 | 3,115,393 | 40,500,109 |
| -1 | -13 | -43 | -53 | -559 | -689 | -1,367 | -2,279 | -17,771 | -29,627 | -58,781 | -72,451 | -764,153 | -941,863 | -3,115,393 | -40,500,109 |
