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 7,144,585, 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 | 7,144,585 | |
| -1 | -7,144,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,144,585.
Example:
1 x 7,144,585 = 7,144,585
and
-1 x -7,144,585 = 7,144,585
Notice both answers equal 7,144,585
With that explanation out of the way, let's continue. Next, we take the number 7,144,585 and divide it by 2:
7,144,585 ÷ 2 = 3,572,292.5
If the quotient is a whole number, then 2 and 3,572,292.5 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 | 7,144,585 | |
| -1 | -7,144,585 |
Now, we try dividing 7,144,585 by 3:
7,144,585 ÷ 3 = 2,381,528.3333
If the quotient is a whole number, then 3 and 2,381,528.3333 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 | 7,144,585 | |
| -1 | -7,144,585 |
Let's try dividing by 4:
7,144,585 ÷ 4 = 1,786,146.25
If the quotient is a whole number, then 4 and 1,786,146.25 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 | 7,144,585 | |
| -1 | 7,144,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 7,039 | 35,195 | 49,273 | 204,131 | 246,365 | 1,020,655 | 1,428,917 | 7,144,585 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -7,039 | -35,195 | -49,273 | -204,131 | -246,365 | -1,020,655 | -1,428,917 | -7,144,585 |
