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 40,314,131, 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 | 40,314,131 | |
| -1 | -40,314,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,314,131.
Example:
1 x 40,314,131 = 40,314,131
and
-1 x -40,314,131 = 40,314,131
Notice both answers equal 40,314,131
With that explanation out of the way, let's continue. Next, we take the number 40,314,131 and divide it by 2:
40,314,131 ÷ 2 = 20,157,065.5
If the quotient is a whole number, then 2 and 20,157,065.5 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 | 40,314,131 | |
| -1 | -40,314,131 |
Now, we try dividing 40,314,131 by 3:
40,314,131 ÷ 3 = 13,438,043.6667
If the quotient is a whole number, then 3 and 13,438,043.6667 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 | 40,314,131 | |
| -1 | -40,314,131 |
Let's try dividing by 4:
40,314,131 ÷ 4 = 10,078,532.75
If the quotient is a whole number, then 4 and 10,078,532.75 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 | 40,314,131 | |
| -1 | 40,314,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 151 | 1,661 | 1,867 | 1,963 | 20,537 | 21,593 | 24,271 | 266,981 | 281,917 | 3,101,087 | 3,664,921 | 40,314,131 |
| -1 | -11 | -13 | -143 | -151 | -1,661 | -1,867 | -1,963 | -20,537 | -21,593 | -24,271 | -266,981 | -281,917 | -3,101,087 | -3,664,921 | -40,314,131 |
