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 40,303,205, 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 | 40,303,205 | |
| -1 | -40,303,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,303,205.
Example:
1 x 40,303,205 = 40,303,205
and
-1 x -40,303,205 = 40,303,205
Notice both answers equal 40,303,205
With that explanation out of the way, let's continue. Next, we take the number 40,303,205 and divide it by 2:
40,303,205 ÷ 2 = 20,151,602.5
If the quotient is a whole number, then 2 and 20,151,602.5 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 | 40,303,205 | |
| -1 | -40,303,205 |
Now, we try dividing 40,303,205 by 3:
40,303,205 ÷ 3 = 13,434,401.6667
If the quotient is a whole number, then 3 and 13,434,401.6667 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 | 40,303,205 | |
| -1 | -40,303,205 |
Let's try dividing by 4:
40,303,205 ÷ 4 = 10,075,801.25
If the quotient is a whole number, then 4 and 10,075,801.25 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 | 40,303,205 | |
| -1 | 40,303,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 47 | 89 | 205 | 235 | 445 | 1,927 | 2,209 | 3,649 | 4,183 | 9,635 | 11,045 | 18,245 | 20,915 | 90,569 | 171,503 | 196,601 | 452,845 | 857,515 | 983,005 | 8,060,641 | 40,303,205 |
| -1 | -5 | -41 | -47 | -89 | -205 | -235 | -445 | -1,927 | -2,209 | -3,649 | -4,183 | -9,635 | -11,045 | -18,245 | -20,915 | -90,569 | -171,503 | -196,601 | -452,845 | -857,515 | -983,005 | -8,060,641 | -40,303,205 |
