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 40,107,347, 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 | 40,107,347 | |
| -1 | -40,107,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,107,347.
Example:
1 x 40,107,347 = 40,107,347
and
-1 x -40,107,347 = 40,107,347
Notice both answers equal 40,107,347
With that explanation out of the way, let's continue. Next, we take the number 40,107,347 and divide it by 2:
40,107,347 ÷ 2 = 20,053,673.5
If the quotient is a whole number, then 2 and 20,053,673.5 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 | 40,107,347 | |
| -1 | -40,107,347 |
Now, we try dividing 40,107,347 by 3:
40,107,347 ÷ 3 = 13,369,115.6667
If the quotient is a whole number, then 3 and 13,369,115.6667 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 | 40,107,347 | |
| -1 | -40,107,347 |
Let's try dividing by 4:
40,107,347 ÷ 4 = 10,026,836.75
If the quotient is a whole number, then 4 and 10,026,836.75 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 | 40,107,347 | |
| -1 | 40,107,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 133 | 301 | 817 | 5,719 | 7,013 | 49,091 | 133,247 | 301,559 | 932,729 | 2,110,913 | 5,729,621 | 40,107,347 |
| -1 | -7 | -19 | -43 | -133 | -301 | -817 | -5,719 | -7,013 | -49,091 | -133,247 | -301,559 | -932,729 | -2,110,913 | -5,729,621 | -40,107,347 |
