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 15,793,645, 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 | 15,793,645 | |
| -1 | -15,793,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,793,645.
Example:
1 x 15,793,645 = 15,793,645
and
-1 x -15,793,645 = 15,793,645
Notice both answers equal 15,793,645
With that explanation out of the way, let's continue. Next, we take the number 15,793,645 and divide it by 2:
15,793,645 ÷ 2 = 7,896,822.5
If the quotient is a whole number, then 2 and 7,896,822.5 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 | 15,793,645 | |
| -1 | -15,793,645 |
Now, we try dividing 15,793,645 by 3:
15,793,645 ÷ 3 = 5,264,548.3333
If the quotient is a whole number, then 3 and 5,264,548.3333 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 | 15,793,645 | |
| -1 | -15,793,645 |
Let's try dividing by 4:
15,793,645 ÷ 4 = 3,948,411.25
If the quotient is a whole number, then 4 and 3,948,411.25 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 | 15,793,645 | |
| -1 | 15,793,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 9,601 | 48,005 | 67,207 | 336,035 | 451,247 | 2,256,235 | 3,158,729 | 15,793,645 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -9,601 | -48,005 | -67,207 | -336,035 | -451,247 | -2,256,235 | -3,158,729 | -15,793,645 |
