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 40,423,055, 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 | 40,423,055 | |
| -1 | -40,423,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,423,055.
Example:
1 x 40,423,055 = 40,423,055
and
-1 x -40,423,055 = 40,423,055
Notice both answers equal 40,423,055
With that explanation out of the way, let's continue. Next, we take the number 40,423,055 and divide it by 2:
40,423,055 ÷ 2 = 20,211,527.5
If the quotient is a whole number, then 2 and 20,211,527.5 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 | 40,423,055 | |
| -1 | -40,423,055 |
Now, we try dividing 40,423,055 by 3:
40,423,055 ÷ 3 = 13,474,351.6667
If the quotient is a whole number, then 3 and 13,474,351.6667 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 | 40,423,055 | |
| -1 | -40,423,055 |
Let's try dividing by 4:
40,423,055 ÷ 4 = 10,105,763.75
If the quotient is a whole number, then 4 and 10,105,763.75 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 | 40,423,055 | |
| -1 | 40,423,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 47 | 185 | 235 | 1,739 | 4,649 | 8,695 | 23,245 | 172,013 | 218,503 | 860,065 | 1,092,515 | 8,084,611 | 40,423,055 |
| -1 | -5 | -37 | -47 | -185 | -235 | -1,739 | -4,649 | -8,695 | -23,245 | -172,013 | -218,503 | -860,065 | -1,092,515 | -8,084,611 | -40,423,055 |
