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 19,673,947, 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 | 19,673,947 | |
| -1 | -19,673,947 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,673,947.
Example:
1 x 19,673,947 = 19,673,947
and
-1 x -19,673,947 = 19,673,947
Notice both answers equal 19,673,947
With that explanation out of the way, let's continue. Next, we take the number 19,673,947 and divide it by 2:
19,673,947 ÷ 2 = 9,836,973.5
If the quotient is a whole number, then 2 and 9,836,973.5 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 | 19,673,947 | |
| -1 | -19,673,947 |
Now, we try dividing 19,673,947 by 3:
19,673,947 ÷ 3 = 6,557,982.3333
If the quotient is a whole number, then 3 and 6,557,982.3333 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 | 19,673,947 | |
| -1 | -19,673,947 |
Let's try dividing by 4:
19,673,947 ÷ 4 = 4,918,486.75
If the quotient is a whole number, then 4 and 4,918,486.75 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 | 19,673,947 | |
| -1 | 19,673,947 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 67 | 391 | 751 | 1,139 | 1,541 | 12,767 | 17,273 | 26,197 | 50,317 | 293,641 | 855,389 | 1,157,291 | 19,673,947 |
| -1 | -17 | -23 | -67 | -391 | -751 | -1,139 | -1,541 | -12,767 | -17,273 | -26,197 | -50,317 | -293,641 | -855,389 | -1,157,291 | -19,673,947 |
