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 26,790,419, 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 | 26,790,419 | |
| -1 | -26,790,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,790,419.
Example:
1 x 26,790,419 = 26,790,419
and
-1 x -26,790,419 = 26,790,419
Notice both answers equal 26,790,419
With that explanation out of the way, let's continue. Next, we take the number 26,790,419 and divide it by 2:
26,790,419 ÷ 2 = 13,395,209.5
If the quotient is a whole number, then 2 and 13,395,209.5 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 | 26,790,419 | |
| -1 | -26,790,419 |
Now, we try dividing 26,790,419 by 3:
26,790,419 ÷ 3 = 8,930,139.6667
If the quotient is a whole number, then 3 and 8,930,139.6667 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 | 26,790,419 | |
| -1 | -26,790,419 |
Let's try dividing by 4:
26,790,419 ÷ 4 = 6,697,604.75
If the quotient is a whole number, then 4 and 6,697,604.75 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 | 26,790,419 | |
| -1 | 26,790,419 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 67 | 547 | 731 | 1,139 | 2,881 | 9,299 | 23,521 | 36,649 | 48,977 | 399,857 | 623,033 | 1,575,907 | 26,790,419 |
| -1 | -17 | -43 | -67 | -547 | -731 | -1,139 | -2,881 | -9,299 | -23,521 | -36,649 | -48,977 | -399,857 | -623,033 | -1,575,907 | -26,790,419 |
