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 1,682,725, 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 | 1,682,725 | |
| -1 | -1,682,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,682,725.
Example:
1 x 1,682,725 = 1,682,725
and
-1 x -1,682,725 = 1,682,725
Notice both answers equal 1,682,725
With that explanation out of the way, let's continue. Next, we take the number 1,682,725 and divide it by 2:
1,682,725 ÷ 2 = 841,362.5
If the quotient is a whole number, then 2 and 841,362.5 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 | 1,682,725 | |
| -1 | -1,682,725 |
Now, we try dividing 1,682,725 by 3:
1,682,725 ÷ 3 = 560,908.3333
If the quotient is a whole number, then 3 and 560,908.3333 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 | 1,682,725 | |
| -1 | -1,682,725 |
Let's try dividing by 4:
1,682,725 ÷ 4 = 420,681.25
If the quotient is a whole number, then 4 and 420,681.25 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 | 1,682,725 | |
| -1 | 1,682,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 29 | 55 | 145 | 211 | 275 | 319 | 725 | 1,055 | 1,595 | 2,321 | 5,275 | 6,119 | 7,975 | 11,605 | 30,595 | 58,025 | 67,309 | 152,975 | 336,545 | 1,682,725 |
| -1 | -5 | -11 | -25 | -29 | -55 | -145 | -211 | -275 | -319 | -725 | -1,055 | -1,595 | -2,321 | -5,275 | -6,119 | -7,975 | -11,605 | -30,595 | -58,025 | -67,309 | -152,975 | -336,545 | -1,682,725 |
