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 1,679,447, 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 | 1,679,447 | |
| -1 | -1,679,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,679,447.
Example:
1 x 1,679,447 = 1,679,447
and
-1 x -1,679,447 = 1,679,447
Notice both answers equal 1,679,447
With that explanation out of the way, let's continue. Next, we take the number 1,679,447 and divide it by 2:
1,679,447 ÷ 2 = 839,723.5
If the quotient is a whole number, then 2 and 839,723.5 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 | 1,679,447 | |
| -1 | -1,679,447 |
Now, we try dividing 1,679,447 by 3:
1,679,447 ÷ 3 = 559,815.6667
If the quotient is a whole number, then 3 and 559,815.6667 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 | 1,679,447 | |
| -1 | -1,679,447 |
Let's try dividing by 4:
1,679,447 ÷ 4 = 419,861.75
If the quotient is a whole number, then 4 and 419,861.75 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 | 1,679,447 | |
| -1 | 1,679,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,283 | 1,309 | 8,981 | 14,113 | 21,811 | 98,791 | 152,677 | 239,921 | 1,679,447 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,283 | -1,309 | -8,981 | -14,113 | -21,811 | -98,791 | -152,677 | -239,921 | -1,679,447 |
