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 1,679,293, 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 | 1,679,293 | |
| -1 | -1,679,293 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,679,293.
Example:
1 x 1,679,293 = 1,679,293
and
-1 x -1,679,293 = 1,679,293
Notice both answers equal 1,679,293
With that explanation out of the way, let's continue. Next, we take the number 1,679,293 and divide it by 2:
1,679,293 ÷ 2 = 839,646.5
If the quotient is a whole number, then 2 and 839,646.5 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 | 1,679,293 | |
| -1 | -1,679,293 |
Now, we try dividing 1,679,293 by 3:
1,679,293 ÷ 3 = 559,764.3333
If the quotient is a whole number, then 3 and 559,764.3333 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 | 1,679,293 | |
| -1 | -1,679,293 |
Let's try dividing by 4:
1,679,293 ÷ 4 = 419,823.25
If the quotient is a whole number, then 4 and 419,823.25 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 | 1,679,293 | |
| -1 | 1,679,293 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 193 | 791 | 1,243 | 1,351 | 2,123 | 8,701 | 14,861 | 21,809 | 152,663 | 239,899 | 1,679,293 |
| -1 | -7 | -11 | -77 | -113 | -193 | -791 | -1,243 | -1,351 | -2,123 | -8,701 | -14,861 | -21,809 | -152,663 | -239,899 | -1,679,293 |
