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 40,111,337, 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 | 40,111,337 | |
| -1 | -40,111,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,111,337.
Example:
1 x 40,111,337 = 40,111,337
and
-1 x -40,111,337 = 40,111,337
Notice both answers equal 40,111,337
With that explanation out of the way, let's continue. Next, we take the number 40,111,337 and divide it by 2:
40,111,337 ÷ 2 = 20,055,668.5
If the quotient is a whole number, then 2 and 20,055,668.5 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 | 40,111,337 | |
| -1 | -40,111,337 |
Now, we try dividing 40,111,337 by 3:
40,111,337 ÷ 3 = 13,370,445.6667
If the quotient is a whole number, then 3 and 13,370,445.6667 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 | 40,111,337 | |
| -1 | -40,111,337 |
Let's try dividing by 4:
40,111,337 ÷ 4 = 10,027,834.25
If the quotient is a whole number, then 4 and 10,027,834.25 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 | 40,111,337 | |
| -1 | 40,111,337 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 191 | 1,337 | 1,579 | 3,629 | 11,053 | 25,403 | 30,001 | 210,007 | 301,589 | 2,111,123 | 5,730,191 | 40,111,337 |
| -1 | -7 | -19 | -133 | -191 | -1,337 | -1,579 | -3,629 | -11,053 | -25,403 | -30,001 | -210,007 | -301,589 | -2,111,123 | -5,730,191 | -40,111,337 |
