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 1,619,675, 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 | 1,619,675 | |
| -1 | -1,619,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,619,675.
Example:
1 x 1,619,675 = 1,619,675
and
-1 x -1,619,675 = 1,619,675
Notice both answers equal 1,619,675
With that explanation out of the way, let's continue. Next, we take the number 1,619,675 and divide it by 2:
1,619,675 ÷ 2 = 809,837.5
If the quotient is a whole number, then 2 and 809,837.5 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 | 1,619,675 | |
| -1 | -1,619,675 |
Now, we try dividing 1,619,675 by 3:
1,619,675 ÷ 3 = 539,891.6667
If the quotient is a whole number, then 3 and 539,891.6667 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 | 1,619,675 | |
| -1 | -1,619,675 |
Let's try dividing by 4:
1,619,675 ÷ 4 = 404,918.75
If the quotient is a whole number, then 4 and 404,918.75 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 | 1,619,675 | |
| -1 | 1,619,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 37 | 85 | 103 | 185 | 425 | 515 | 629 | 925 | 1,751 | 2,575 | 3,145 | 3,811 | 8,755 | 15,725 | 19,055 | 43,775 | 64,787 | 95,275 | 323,935 | 1,619,675 |
| -1 | -5 | -17 | -25 | -37 | -85 | -103 | -185 | -425 | -515 | -629 | -925 | -1,751 | -2,575 | -3,145 | -3,811 | -8,755 | -15,725 | -19,055 | -43,775 | -64,787 | -95,275 | -323,935 | -1,619,675 |
