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 2,390,095, 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 | 2,390,095 | |
| -1 | -2,390,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,390,095.
Example:
1 x 2,390,095 = 2,390,095
and
-1 x -2,390,095 = 2,390,095
Notice both answers equal 2,390,095
With that explanation out of the way, let's continue. Next, we take the number 2,390,095 and divide it by 2:
2,390,095 ÷ 2 = 1,195,047.5
If the quotient is a whole number, then 2 and 1,195,047.5 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 | 2,390,095 | |
| -1 | -2,390,095 |
Now, we try dividing 2,390,095 by 3:
2,390,095 ÷ 3 = 796,698.3333
If the quotient is a whole number, then 3 and 796,698.3333 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 | 2,390,095 | |
| -1 | -2,390,095 |
Let's try dividing by 4:
2,390,095 ÷ 4 = 597,523.75
If the quotient is a whole number, then 4 and 597,523.75 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 | 2,390,095 | |
| -1 | 2,390,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 89 | 131 | 205 | 445 | 655 | 3,649 | 5,371 | 11,659 | 18,245 | 26,855 | 58,295 | 478,019 | 2,390,095 |
| -1 | -5 | -41 | -89 | -131 | -205 | -445 | -655 | -3,649 | -5,371 | -11,659 | -18,245 | -26,855 | -58,295 | -478,019 | -2,390,095 |
