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 1,541,815, 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 | 1,541,815 | |
| -1 | -1,541,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,541,815.
Example:
1 x 1,541,815 = 1,541,815
and
-1 x -1,541,815 = 1,541,815
Notice both answers equal 1,541,815
With that explanation out of the way, let's continue. Next, we take the number 1,541,815 and divide it by 2:
1,541,815 ÷ 2 = 770,907.5
If the quotient is a whole number, then 2 and 770,907.5 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 | 1,541,815 | |
| -1 | -1,541,815 |
Now, we try dividing 1,541,815 by 3:
1,541,815 ÷ 3 = 513,938.3333
If the quotient is a whole number, then 3 and 513,938.3333 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 | 1,541,815 | |
| -1 | -1,541,815 |
Let's try dividing by 4:
1,541,815 ÷ 4 = 385,453.75
If the quotient is a whole number, then 4 and 385,453.75 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 | 1,541,815 | |
| -1 | 1,541,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 97 | 187 | 289 | 485 | 935 | 1,067 | 1,445 | 1,649 | 3,179 | 5,335 | 8,245 | 15,895 | 18,139 | 28,033 | 90,695 | 140,165 | 308,363 | 1,541,815 |
| -1 | -5 | -11 | -17 | -55 | -85 | -97 | -187 | -289 | -485 | -935 | -1,067 | -1,445 | -1,649 | -3,179 | -5,335 | -8,245 | -15,895 | -18,139 | -28,033 | -90,695 | -140,165 | -308,363 | -1,541,815 |
