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 40,333,145, 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 | 40,333,145 | |
| -1 | -40,333,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,333,145.
Example:
1 x 40,333,145 = 40,333,145
and
-1 x -40,333,145 = 40,333,145
Notice both answers equal 40,333,145
With that explanation out of the way, let's continue. Next, we take the number 40,333,145 and divide it by 2:
40,333,145 ÷ 2 = 20,166,572.5
If the quotient is a whole number, then 2 and 20,166,572.5 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 | 40,333,145 | |
| -1 | -40,333,145 |
Now, we try dividing 40,333,145 by 3:
40,333,145 ÷ 3 = 13,444,381.6667
If the quotient is a whole number, then 3 and 13,444,381.6667 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 | 40,333,145 | |
| -1 | -40,333,145 |
Let's try dividing by 4:
40,333,145 ÷ 4 = 10,083,286.25
If the quotient is a whole number, then 4 and 10,083,286.25 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 | 40,333,145 | |
| -1 | 40,333,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 4,255 | 9,479 | 47,395 | 218,017 | 350,723 | 1,090,085 | 1,753,615 | 8,066,629 | 40,333,145 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -4,255 | -9,479 | -47,395 | -218,017 | -350,723 | -1,090,085 | -1,753,615 | -8,066,629 | -40,333,145 |
