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 1,821,325, 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 | 1,821,325 | |
| -1 | -1,821,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,821,325.
Example:
1 x 1,821,325 = 1,821,325
and
-1 x -1,821,325 = 1,821,325
Notice both answers equal 1,821,325
With that explanation out of the way, let's continue. Next, we take the number 1,821,325 and divide it by 2:
1,821,325 ÷ 2 = 910,662.5
If the quotient is a whole number, then 2 and 910,662.5 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 | 1,821,325 | |
| -1 | -1,821,325 |
Now, we try dividing 1,821,325 by 3:
1,821,325 ÷ 3 = 607,108.3333
If the quotient is a whole number, then 3 and 607,108.3333 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 | 1,821,325 | |
| -1 | -1,821,325 |
Let's try dividing by 4:
1,821,325 ÷ 4 = 455,331.25
If the quotient is a whole number, then 4 and 455,331.25 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 | 1,821,325 | |
| -1 | 1,821,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 37 | 55 | 179 | 185 | 275 | 407 | 895 | 925 | 1,969 | 2,035 | 4,475 | 6,623 | 9,845 | 10,175 | 33,115 | 49,225 | 72,853 | 165,575 | 364,265 | 1,821,325 |
| -1 | -5 | -11 | -25 | -37 | -55 | -179 | -185 | -275 | -407 | -895 | -925 | -1,969 | -2,035 | -4,475 | -6,623 | -9,845 | -10,175 | -33,115 | -49,225 | -72,853 | -165,575 | -364,265 | -1,821,325 |
