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 1,421,735, 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 | 1,421,735 | |
| -1 | -1,421,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,421,735.
Example:
1 x 1,421,735 = 1,421,735
and
-1 x -1,421,735 = 1,421,735
Notice both answers equal 1,421,735
With that explanation out of the way, let's continue. Next, we take the number 1,421,735 and divide it by 2:
1,421,735 ÷ 2 = 710,867.5
If the quotient is a whole number, then 2 and 710,867.5 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 | 1,421,735 | |
| -1 | -1,421,735 |
Now, we try dividing 1,421,735 by 3:
1,421,735 ÷ 3 = 473,911.6667
If the quotient is a whole number, then 3 and 473,911.6667 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 | 1,421,735 | |
| -1 | -1,421,735 |
Let's try dividing by 4:
1,421,735 ÷ 4 = 355,433.75
If the quotient is a whole number, then 4 and 355,433.75 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 | 1,421,735 | |
| -1 | 1,421,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 829 | 1,715 | 4,145 | 5,803 | 29,015 | 40,621 | 203,105 | 284,347 | 1,421,735 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -829 | -1,715 | -4,145 | -5,803 | -29,015 | -40,621 | -203,105 | -284,347 | -1,421,735 |
