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 39,302,963, 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 | 39,302,963 | |
| -1 | -39,302,963 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,302,963.
Example:
1 x 39,302,963 = 39,302,963
and
-1 x -39,302,963 = 39,302,963
Notice both answers equal 39,302,963
With that explanation out of the way, let's continue. Next, we take the number 39,302,963 and divide it by 2:
39,302,963 ÷ 2 = 19,651,481.5
If the quotient is a whole number, then 2 and 19,651,481.5 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 | 39,302,963 | |
| -1 | -39,302,963 |
Now, we try dividing 39,302,963 by 3:
39,302,963 ÷ 3 = 13,100,987.6667
If the quotient is a whole number, then 3 and 13,100,987.6667 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 | 39,302,963 | |
| -1 | -39,302,963 |
Let's try dividing by 4:
39,302,963 ÷ 4 = 9,825,740.75
If the quotient is a whole number, then 4 and 9,825,740.75 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 | 39,302,963 | |
| -1 | 39,302,963 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 17,383 | 121,681 | 295,511 | 330,277 | 2,068,577 | 2,311,939 | 5,614,709 | 39,302,963 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -17,383 | -121,681 | -295,511 | -330,277 | -2,068,577 | -2,311,939 | -5,614,709 | -39,302,963 |
