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 1,626,373, 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 | 1,626,373 | |
| -1 | -1,626,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,626,373.
Example:
1 x 1,626,373 = 1,626,373
and
-1 x -1,626,373 = 1,626,373
Notice both answers equal 1,626,373
With that explanation out of the way, let's continue. Next, we take the number 1,626,373 and divide it by 2:
1,626,373 ÷ 2 = 813,186.5
If the quotient is a whole number, then 2 and 813,186.5 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 | 1,626,373 | |
| -1 | -1,626,373 |
Now, we try dividing 1,626,373 by 3:
1,626,373 ÷ 3 = 542,124.3333
If the quotient is a whole number, then 3 and 542,124.3333 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 | 1,626,373 | |
| -1 | -1,626,373 |
Let's try dividing by 4:
1,626,373 ÷ 4 = 406,593.25
If the quotient is a whole number, then 4 and 406,593.25 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 | 1,626,373 | |
| -1 | 1,626,373 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 79 | 119 | 173 | 553 | 1,211 | 1,343 | 2,941 | 9,401 | 13,667 | 20,587 | 95,669 | 232,339 | 1,626,373 |
| -1 | -7 | -17 | -79 | -119 | -173 | -553 | -1,211 | -1,343 | -2,941 | -9,401 | -13,667 | -20,587 | -95,669 | -232,339 | -1,626,373 |
