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 1,802,119, 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 | 1,802,119 | |
| -1 | -1,802,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,802,119.
Example:
1 x 1,802,119 = 1,802,119
and
-1 x -1,802,119 = 1,802,119
Notice both answers equal 1,802,119
With that explanation out of the way, let's continue. Next, we take the number 1,802,119 and divide it by 2:
1,802,119 ÷ 2 = 901,059.5
If the quotient is a whole number, then 2 and 901,059.5 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 | 1,802,119 | |
| -1 | -1,802,119 |
Now, we try dividing 1,802,119 by 3:
1,802,119 ÷ 3 = 600,706.3333
If the quotient is a whole number, then 3 and 600,706.3333 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 | 1,802,119 | |
| -1 | -1,802,119 |
Let's try dividing by 4:
1,802,119 ÷ 4 = 450,529.75
If the quotient is a whole number, then 4 and 450,529.75 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 | 1,802,119 | |
| -1 | 1,802,119 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 187 | 253 | 391 | 419 | 4,301 | 4,609 | 7,123 | 9,637 | 78,353 | 106,007 | 163,829 | 1,802,119 |
| -1 | -11 | -17 | -23 | -187 | -253 | -391 | -419 | -4,301 | -4,609 | -7,123 | -9,637 | -78,353 | -106,007 | -163,829 | -1,802,119 |
