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 1,840,625, 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 | 1,840,625 | |
| -1 | -1,840,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,840,625.
Example:
1 x 1,840,625 = 1,840,625
and
-1 x -1,840,625 = 1,840,625
Notice both answers equal 1,840,625
With that explanation out of the way, let's continue. Next, we take the number 1,840,625 and divide it by 2:
1,840,625 ÷ 2 = 920,312.5
If the quotient is a whole number, then 2 and 920,312.5 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 | 1,840,625 | |
| -1 | -1,840,625 |
Now, we try dividing 1,840,625 by 3:
1,840,625 ÷ 3 = 613,541.6667
If the quotient is a whole number, then 3 and 613,541.6667 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 | 1,840,625 | |
| -1 | -1,840,625 |
Let's try dividing by 4:
1,840,625 ÷ 4 = 460,156.25
If the quotient is a whole number, then 4 and 460,156.25 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 | 1,840,625 | |
| -1 | 1,840,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 31 | 95 | 125 | 155 | 475 | 589 | 625 | 775 | 2,375 | 2,945 | 3,125 | 3,875 | 11,875 | 14,725 | 19,375 | 59,375 | 73,625 | 96,875 | 368,125 | 1,840,625 |
| -1 | -5 | -19 | -25 | -31 | -95 | -125 | -155 | -475 | -589 | -625 | -775 | -2,375 | -2,945 | -3,125 | -3,875 | -11,875 | -14,725 | -19,375 | -59,375 | -73,625 | -96,875 | -368,125 | -1,840,625 |
