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 1,967,665, 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 | 1,967,665 | |
| -1 | -1,967,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,967,665.
Example:
1 x 1,967,665 = 1,967,665
and
-1 x -1,967,665 = 1,967,665
Notice both answers equal 1,967,665
With that explanation out of the way, let's continue. Next, we take the number 1,967,665 and divide it by 2:
1,967,665 ÷ 2 = 983,832.5
If the quotient is a whole number, then 2 and 983,832.5 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 | 1,967,665 | |
| -1 | -1,967,665 |
Now, we try dividing 1,967,665 by 3:
1,967,665 ÷ 3 = 655,888.3333
If the quotient is a whole number, then 3 and 655,888.3333 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 | 1,967,665 | |
| -1 | -1,967,665 |
Let's try dividing by 4:
1,967,665 ÷ 4 = 491,916.25
If the quotient is a whole number, then 4 and 491,916.25 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 | 1,967,665 | |
| -1 | 1,967,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 3,307 | 16,535 | 23,149 | 56,219 | 115,745 | 281,095 | 393,533 | 1,967,665 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -3,307 | -16,535 | -23,149 | -56,219 | -115,745 | -281,095 | -393,533 | -1,967,665 |
