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 1,421,675, 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 | 1,421,675 | |
| -1 | -1,421,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,421,675.
Example:
1 x 1,421,675 = 1,421,675
and
-1 x -1,421,675 = 1,421,675
Notice both answers equal 1,421,675
With that explanation out of the way, let's continue. Next, we take the number 1,421,675 and divide it by 2:
1,421,675 ÷ 2 = 710,837.5
If the quotient is a whole number, then 2 and 710,837.5 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 | 1,421,675 | |
| -1 | -1,421,675 |
Now, we try dividing 1,421,675 by 3:
1,421,675 ÷ 3 = 473,891.6667
If the quotient is a whole number, then 3 and 473,891.6667 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 | 1,421,675 | |
| -1 | -1,421,675 |
Let's try dividing by 4:
1,421,675 ÷ 4 = 355,418.75
If the quotient is a whole number, then 4 and 355,418.75 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 | 1,421,675 | |
| -1 | 1,421,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 41 | 73 | 95 | 205 | 365 | 475 | 779 | 1,025 | 1,387 | 1,825 | 2,993 | 3,895 | 6,935 | 14,965 | 19,475 | 34,675 | 56,867 | 74,825 | 284,335 | 1,421,675 |
| -1 | -5 | -19 | -25 | -41 | -73 | -95 | -205 | -365 | -475 | -779 | -1,025 | -1,387 | -1,825 | -2,993 | -3,895 | -6,935 | -14,965 | -19,475 | -34,675 | -56,867 | -74,825 | -284,335 | -1,421,675 |
