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 1,968,995, 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 | 1,968,995 | |
| -1 | -1,968,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,968,995.
Example:
1 x 1,968,995 = 1,968,995
and
-1 x -1,968,995 = 1,968,995
Notice both answers equal 1,968,995
With that explanation out of the way, let's continue. Next, we take the number 1,968,995 and divide it by 2:
1,968,995 ÷ 2 = 984,497.5
If the quotient is a whole number, then 2 and 984,497.5 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 | 1,968,995 | |
| -1 | -1,968,995 |
Now, we try dividing 1,968,995 by 3:
1,968,995 ÷ 3 = 656,331.6667
If the quotient is a whole number, then 3 and 656,331.6667 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 | 1,968,995 | |
| -1 | -1,968,995 |
Let's try dividing by 4:
1,968,995 ÷ 4 = 492,248.75
If the quotient is a whole number, then 4 and 492,248.75 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 | 1,968,995 | |
| -1 | 1,968,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 101 | 505 | 557 | 707 | 2,785 | 3,535 | 3,899 | 19,495 | 56,257 | 281,285 | 393,799 | 1,968,995 |
| -1 | -5 | -7 | -35 | -101 | -505 | -557 | -707 | -2,785 | -3,535 | -3,899 | -19,495 | -56,257 | -281,285 | -393,799 | -1,968,995 |
