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 1,479,731, 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 | 1,479,731 | |
| -1 | -1,479,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,479,731.
Example:
1 x 1,479,731 = 1,479,731
and
-1 x -1,479,731 = 1,479,731
Notice both answers equal 1,479,731
With that explanation out of the way, let's continue. Next, we take the number 1,479,731 and divide it by 2:
1,479,731 ÷ 2 = 739,865.5
If the quotient is a whole number, then 2 and 739,865.5 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 | 1,479,731 | |
| -1 | -1,479,731 |
Now, we try dividing 1,479,731 by 3:
1,479,731 ÷ 3 = 493,243.6667
If the quotient is a whole number, then 3 and 493,243.6667 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 | 1,479,731 | |
| -1 | -1,479,731 |
Let's try dividing by 4:
1,479,731 ÷ 4 = 369,932.75
If the quotient is a whole number, then 4 and 369,932.75 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 | 1,479,731 | |
| -1 | 1,479,731 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 187 | 193 | 451 | 697 | 2,123 | 3,281 | 7,667 | 7,913 | 36,091 | 87,043 | 134,521 | 1,479,731 |
| -1 | -11 | -17 | -41 | -187 | -193 | -451 | -697 | -2,123 | -3,281 | -7,667 | -7,913 | -36,091 | -87,043 | -134,521 | -1,479,731 |
