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 1,421,609, 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 | 1,421,609 | |
| -1 | -1,421,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,421,609.
Example:
1 x 1,421,609 = 1,421,609
and
-1 x -1,421,609 = 1,421,609
Notice both answers equal 1,421,609
With that explanation out of the way, let's continue. Next, we take the number 1,421,609 and divide it by 2:
1,421,609 ÷ 2 = 710,804.5
If the quotient is a whole number, then 2 and 710,804.5 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 | 1,421,609 | |
| -1 | -1,421,609 |
Now, we try dividing 1,421,609 by 3:
1,421,609 ÷ 3 = 473,869.6667
If the quotient is a whole number, then 3 and 473,869.6667 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 | 1,421,609 | |
| -1 | -1,421,609 |
Let's try dividing by 4:
1,421,609 ÷ 4 = 355,402.25
If the quotient is a whole number, then 4 and 355,402.25 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 | 1,421,609 | |
| -1 | 1,421,609 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 47 | 149 | 203 | 329 | 1,043 | 1,363 | 4,321 | 7,003 | 9,541 | 30,247 | 49,021 | 203,087 | 1,421,609 |
| -1 | -7 | -29 | -47 | -149 | -203 | -329 | -1,043 | -1,363 | -4,321 | -7,003 | -9,541 | -30,247 | -49,021 | -203,087 | -1,421,609 |
