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 1,851,815, 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 | 1,851,815 | |
| -1 | -1,851,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,851,815.
Example:
1 x 1,851,815 = 1,851,815
and
-1 x -1,851,815 = 1,851,815
Notice both answers equal 1,851,815
With that explanation out of the way, let's continue. Next, we take the number 1,851,815 and divide it by 2:
1,851,815 ÷ 2 = 925,907.5
If the quotient is a whole number, then 2 and 925,907.5 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 | 1,851,815 | |
| -1 | -1,851,815 |
Now, we try dividing 1,851,815 by 3:
1,851,815 ÷ 3 = 617,271.6667
If the quotient is a whole number, then 3 and 617,271.6667 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 | 1,851,815 | |
| -1 | -1,851,815 |
Let's try dividing by 4:
1,851,815 ÷ 4 = 462,953.75
If the quotient is a whole number, then 4 and 462,953.75 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 | 1,851,815 | |
| -1 | 1,851,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 157 | 337 | 785 | 1,099 | 1,685 | 2,359 | 5,495 | 11,795 | 52,909 | 264,545 | 370,363 | 1,851,815 |
| -1 | -5 | -7 | -35 | -157 | -337 | -785 | -1,099 | -1,685 | -2,359 | -5,495 | -11,795 | -52,909 | -264,545 | -370,363 | -1,851,815 |
