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 40,043,375, 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 | 40,043,375 | |
| -1 | -40,043,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,043,375.
Example:
1 x 40,043,375 = 40,043,375
and
-1 x -40,043,375 = 40,043,375
Notice both answers equal 40,043,375
With that explanation out of the way, let's continue. Next, we take the number 40,043,375 and divide it by 2:
40,043,375 ÷ 2 = 20,021,687.5
If the quotient is a whole number, then 2 and 20,021,687.5 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 | 40,043,375 | |
| -1 | -40,043,375 |
Now, we try dividing 40,043,375 by 3:
40,043,375 ÷ 3 = 13,347,791.6667
If the quotient is a whole number, then 3 and 13,347,791.6667 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 | 40,043,375 | |
| -1 | -40,043,375 |
Let's try dividing by 4:
40,043,375 ÷ 4 = 10,010,843.75
If the quotient is a whole number, then 4 and 10,010,843.75 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 | 40,043,375 | |
| -1 | 40,043,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 563 | 569 | 2,815 | 2,845 | 14,075 | 14,225 | 70,375 | 71,125 | 320,347 | 1,601,735 | 8,008,675 | 40,043,375 |
| -1 | -5 | -25 | -125 | -563 | -569 | -2,815 | -2,845 | -14,075 | -14,225 | -70,375 | -71,125 | -320,347 | -1,601,735 | -8,008,675 | -40,043,375 |
