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 40,342,211, 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 | 40,342,211 | |
| -1 | -40,342,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,342,211.
Example:
1 x 40,342,211 = 40,342,211
and
-1 x -40,342,211 = 40,342,211
Notice both answers equal 40,342,211
With that explanation out of the way, let's continue. Next, we take the number 40,342,211 and divide it by 2:
40,342,211 ÷ 2 = 20,171,105.5
If the quotient is a whole number, then 2 and 20,171,105.5 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 | 40,342,211 | |
| -1 | -40,342,211 |
Now, we try dividing 40,342,211 by 3:
40,342,211 ÷ 3 = 13,447,403.6667
If the quotient is a whole number, then 3 and 13,447,403.6667 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 | 40,342,211 | |
| -1 | -40,342,211 |
Let's try dividing by 4:
40,342,211 ÷ 4 = 10,085,552.75
If the quotient is a whole number, then 4 and 10,085,552.75 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 | 40,342,211 | |
| -1 | 40,342,211 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 193 | 1,351 | 2,297 | 2,509 | 16,079 | 17,563 | 29,861 | 209,027 | 443,321 | 3,103,247 | 5,763,173 | 40,342,211 |
| -1 | -7 | -13 | -91 | -193 | -1,351 | -2,297 | -2,509 | -16,079 | -17,563 | -29,861 | -209,027 | -443,321 | -3,103,247 | -5,763,173 | -40,342,211 |
