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 1,976,135, 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 | 1,976,135 | |
| -1 | -1,976,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,976,135.
Example:
1 x 1,976,135 = 1,976,135
and
-1 x -1,976,135 = 1,976,135
Notice both answers equal 1,976,135
With that explanation out of the way, let's continue. Next, we take the number 1,976,135 and divide it by 2:
1,976,135 ÷ 2 = 988,067.5
If the quotient is a whole number, then 2 and 988,067.5 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 | 1,976,135 | |
| -1 | -1,976,135 |
Now, we try dividing 1,976,135 by 3:
1,976,135 ÷ 3 = 658,711.6667
If the quotient is a whole number, then 3 and 658,711.6667 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 | 1,976,135 | |
| -1 | -1,976,135 |
Let's try dividing by 4:
1,976,135 ÷ 4 = 494,033.75
If the quotient is a whole number, then 4 and 494,033.75 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 | 1,976,135 | |
| -1 | 1,976,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 131 | 431 | 655 | 917 | 2,155 | 3,017 | 4,585 | 15,085 | 56,461 | 282,305 | 395,227 | 1,976,135 |
| -1 | -5 | -7 | -35 | -131 | -431 | -655 | -917 | -2,155 | -3,017 | -4,585 | -15,085 | -56,461 | -282,305 | -395,227 | -1,976,135 |
