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 1,342,145, 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 | 1,342,145 | |
| -1 | -1,342,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,342,145.
Example:
1 x 1,342,145 = 1,342,145
and
-1 x -1,342,145 = 1,342,145
Notice both answers equal 1,342,145
With that explanation out of the way, let's continue. Next, we take the number 1,342,145 and divide it by 2:
1,342,145 ÷ 2 = 671,072.5
If the quotient is a whole number, then 2 and 671,072.5 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 | 1,342,145 | |
| -1 | -1,342,145 |
Now, we try dividing 1,342,145 by 3:
1,342,145 ÷ 3 = 447,381.6667
If the quotient is a whole number, then 3 and 447,381.6667 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 | 1,342,145 | |
| -1 | -1,342,145 |
Let's try dividing by 4:
1,342,145 ÷ 4 = 335,536.25
If the quotient is a whole number, then 4 and 335,536.25 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 | 1,342,145 | |
| -1 | 1,342,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 1,237 | 6,185 | 8,659 | 38,347 | 43,295 | 191,735 | 268,429 | 1,342,145 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -1,237 | -6,185 | -8,659 | -38,347 | -43,295 | -191,735 | -268,429 | -1,342,145 |
