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 19,627,867, 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 | 19,627,867 | |
| -1 | -19,627,867 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,627,867.
Example:
1 x 19,627,867 = 19,627,867
and
-1 x -19,627,867 = 19,627,867
Notice both answers equal 19,627,867
With that explanation out of the way, let's continue. Next, we take the number 19,627,867 and divide it by 2:
19,627,867 ÷ 2 = 9,813,933.5
If the quotient is a whole number, then 2 and 9,813,933.5 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 | 19,627,867 | |
| -1 | -19,627,867 |
Now, we try dividing 19,627,867 by 3:
19,627,867 ÷ 3 = 6,542,622.3333
If the quotient is a whole number, then 3 and 6,542,622.3333 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 | 19,627,867 | |
| -1 | -19,627,867 |
Let's try dividing by 4:
19,627,867 ÷ 4 = 4,906,966.75
If the quotient is a whole number, then 4 and 4,906,966.75 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 | 19,627,867 | |
| -1 | 19,627,867 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 31 | 203 | 217 | 899 | 3,119 | 6,293 | 21,833 | 90,451 | 96,689 | 633,157 | 676,823 | 2,803,981 | 19,627,867 |
| -1 | -7 | -29 | -31 | -203 | -217 | -899 | -3,119 | -6,293 | -21,833 | -90,451 | -96,689 | -633,157 | -676,823 | -2,803,981 | -19,627,867 |
