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 1,637,195, 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 | 1,637,195 | |
| -1 | -1,637,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,637,195.
Example:
1 x 1,637,195 = 1,637,195
and
-1 x -1,637,195 = 1,637,195
Notice both answers equal 1,637,195
With that explanation out of the way, let's continue. Next, we take the number 1,637,195 and divide it by 2:
1,637,195 ÷ 2 = 818,597.5
If the quotient is a whole number, then 2 and 818,597.5 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 | 1,637,195 | |
| -1 | -1,637,195 |
Now, we try dividing 1,637,195 by 3:
1,637,195 ÷ 3 = 545,731.6667
If the quotient is a whole number, then 3 and 545,731.6667 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 | 1,637,195 | |
| -1 | -1,637,195 |
Let's try dividing by 4:
1,637,195 ÷ 4 = 409,298.75
If the quotient is a whole number, then 4 and 409,298.75 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 | 1,637,195 | |
| -1 | 1,637,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 1,613 | 8,065 | 11,291 | 46,777 | 56,455 | 233,885 | 327,439 | 1,637,195 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -1,613 | -8,065 | -11,291 | -46,777 | -56,455 | -233,885 | -327,439 | -1,637,195 |
