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 1,662,739, 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 | 1,662,739 | |
| -1 | -1,662,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,662,739.
Example:
1 x 1,662,739 = 1,662,739
and
-1 x -1,662,739 = 1,662,739
Notice both answers equal 1,662,739
With that explanation out of the way, let's continue. Next, we take the number 1,662,739 and divide it by 2:
1,662,739 ÷ 2 = 831,369.5
If the quotient is a whole number, then 2 and 831,369.5 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 | 1,662,739 | |
| -1 | -1,662,739 |
Now, we try dividing 1,662,739 by 3:
1,662,739 ÷ 3 = 554,246.3333
If the quotient is a whole number, then 3 and 554,246.3333 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 | 1,662,739 | |
| -1 | -1,662,739 |
Let's try dividing by 4:
1,662,739 ÷ 4 = 415,684.75
If the quotient is a whole number, then 4 and 415,684.75 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 | 1,662,739 | |
| -1 | 1,662,739 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 67 | 83 | 299 | 871 | 1,079 | 1,541 | 1,909 | 5,561 | 20,033 | 24,817 | 72,293 | 127,903 | 1,662,739 |
| -1 | -13 | -23 | -67 | -83 | -299 | -871 | -1,079 | -1,541 | -1,909 | -5,561 | -20,033 | -24,817 | -72,293 | -127,903 | -1,662,739 |
