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 40,086,067, 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 | 40,086,067 | |
| -1 | -40,086,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,086,067.
Example:
1 x 40,086,067 = 40,086,067
and
-1 x -40,086,067 = 40,086,067
Notice both answers equal 40,086,067
With that explanation out of the way, let's continue. Next, we take the number 40,086,067 and divide it by 2:
40,086,067 ÷ 2 = 20,043,033.5
If the quotient is a whole number, then 2 and 20,043,033.5 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 | 40,086,067 | |
| -1 | -40,086,067 |
Now, we try dividing 40,086,067 by 3:
40,086,067 ÷ 3 = 13,362,022.3333
If the quotient is a whole number, then 3 and 13,362,022.3333 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 | 40,086,067 | |
| -1 | -40,086,067 |
Let's try dividing by 4:
40,086,067 ÷ 4 = 10,021,516.75
If the quotient is a whole number, then 4 and 10,021,516.75 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 | 40,086,067 | |
| -1 | 40,086,067 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 343 | 931 | 6,151 | 6,517 | 43,057 | 116,869 | 301,399 | 818,083 | 2,109,793 | 5,726,581 | 40,086,067 |
| -1 | -7 | -19 | -49 | -133 | -343 | -931 | -6,151 | -6,517 | -43,057 | -116,869 | -301,399 | -818,083 | -2,109,793 | -5,726,581 | -40,086,067 |
