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 1,964,875, 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 | 1,964,875 | |
| -1 | -1,964,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,964,875.
Example:
1 x 1,964,875 = 1,964,875
and
-1 x -1,964,875 = 1,964,875
Notice both answers equal 1,964,875
With that explanation out of the way, let's continue. Next, we take the number 1,964,875 and divide it by 2:
1,964,875 ÷ 2 = 982,437.5
If the quotient is a whole number, then 2 and 982,437.5 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 | 1,964,875 | |
| -1 | -1,964,875 |
Now, we try dividing 1,964,875 by 3:
1,964,875 ÷ 3 = 654,958.3333
If the quotient is a whole number, then 3 and 654,958.3333 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 | 1,964,875 | |
| -1 | -1,964,875 |
Let's try dividing by 4:
1,964,875 ÷ 4 = 491,218.75
If the quotient is a whole number, then 4 and 491,218.75 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 | 1,964,875 | |
| -1 | 1,964,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 1,429 | 7,145 | 15,719 | 35,725 | 78,595 | 178,625 | 392,975 | 1,964,875 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -1,429 | -7,145 | -15,719 | -35,725 | -78,595 | -178,625 | -392,975 | -1,964,875 |
