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 1,820,545, 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 | 1,820,545 | |
| -1 | -1,820,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,820,545.
Example:
1 x 1,820,545 = 1,820,545
and
-1 x -1,820,545 = 1,820,545
Notice both answers equal 1,820,545
With that explanation out of the way, let's continue. Next, we take the number 1,820,545 and divide it by 2:
1,820,545 ÷ 2 = 910,272.5
If the quotient is a whole number, then 2 and 910,272.5 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 | 1,820,545 | |
| -1 | -1,820,545 |
Now, we try dividing 1,820,545 by 3:
1,820,545 ÷ 3 = 606,848.3333
If the quotient is a whole number, then 3 and 606,848.3333 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 | 1,820,545 | |
| -1 | -1,820,545 |
Let's try dividing by 4:
1,820,545 ÷ 4 = 455,136.25
If the quotient is a whole number, then 4 and 455,136.25 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 | 1,820,545 | |
| -1 | 1,820,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 61 | 127 | 235 | 305 | 635 | 2,867 | 5,969 | 7,747 | 14,335 | 29,845 | 38,735 | 364,109 | 1,820,545 |
| -1 | -5 | -47 | -61 | -127 | -235 | -305 | -635 | -2,867 | -5,969 | -7,747 | -14,335 | -29,845 | -38,735 | -364,109 | -1,820,545 |
