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 1,853,545, 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 | 1,853,545 | |
| -1 | -1,853,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,853,545.
Example:
1 x 1,853,545 = 1,853,545
and
-1 x -1,853,545 = 1,853,545
Notice both answers equal 1,853,545
With that explanation out of the way, let's continue. Next, we take the number 1,853,545 and divide it by 2:
1,853,545 ÷ 2 = 926,772.5
If the quotient is a whole number, then 2 and 926,772.5 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 | 1,853,545 | |
| -1 | -1,853,545 |
Now, we try dividing 1,853,545 by 3:
1,853,545 ÷ 3 = 617,848.3333
If the quotient is a whole number, then 3 and 617,848.3333 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 | 1,853,545 | |
| -1 | -1,853,545 |
Let's try dividing by 4:
1,853,545 ÷ 4 = 463,386.25
If the quotient is a whole number, then 4 and 463,386.25 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 | 1,853,545 | |
| -1 | 1,853,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 109 | 179 | 545 | 895 | 2,071 | 3,401 | 10,355 | 17,005 | 19,511 | 97,555 | 370,709 | 1,853,545 |
| -1 | -5 | -19 | -95 | -109 | -179 | -545 | -895 | -2,071 | -3,401 | -10,355 | -17,005 | -19,511 | -97,555 | -370,709 | -1,853,545 |
