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 1,944,475, 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 | 1,944,475 | |
| -1 | -1,944,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,944,475.
Example:
1 x 1,944,475 = 1,944,475
and
-1 x -1,944,475 = 1,944,475
Notice both answers equal 1,944,475
With that explanation out of the way, let's continue. Next, we take the number 1,944,475 and divide it by 2:
1,944,475 ÷ 2 = 972,237.5
If the quotient is a whole number, then 2 and 972,237.5 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 | 1,944,475 | |
| -1 | -1,944,475 |
Now, we try dividing 1,944,475 by 3:
1,944,475 ÷ 3 = 648,158.3333
If the quotient is a whole number, then 3 and 648,158.3333 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 | 1,944,475 | |
| -1 | -1,944,475 |
Let's try dividing by 4:
1,944,475 ÷ 4 = 486,118.75
If the quotient is a whole number, then 4 and 486,118.75 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 | 1,944,475 | |
| -1 | 1,944,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 31 | 65 | 155 | 193 | 325 | 403 | 775 | 965 | 2,015 | 2,509 | 4,825 | 5,983 | 10,075 | 12,545 | 29,915 | 62,725 | 77,779 | 149,575 | 388,895 | 1,944,475 |
| -1 | -5 | -13 | -25 | -31 | -65 | -155 | -193 | -325 | -403 | -775 | -965 | -2,015 | -2,509 | -4,825 | -5,983 | -10,075 | -12,545 | -29,915 | -62,725 | -77,779 | -149,575 | -388,895 | -1,944,475 |
