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 3,815,095, 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 | 3,815,095 | |
| -1 | -3,815,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,815,095.
Example:
1 x 3,815,095 = 3,815,095
and
-1 x -3,815,095 = 3,815,095
Notice both answers equal 3,815,095
With that explanation out of the way, let's continue. Next, we take the number 3,815,095 and divide it by 2:
3,815,095 ÷ 2 = 1,907,547.5
If the quotient is a whole number, then 2 and 1,907,547.5 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 | 3,815,095 | |
| -1 | -3,815,095 |
Now, we try dividing 3,815,095 by 3:
3,815,095 ÷ 3 = 1,271,698.3333
If the quotient is a whole number, then 3 and 1,271,698.3333 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 | 3,815,095 | |
| -1 | -3,815,095 |
Let's try dividing by 4:
3,815,095 ÷ 4 = 953,773.75
If the quotient is a whole number, then 4 and 953,773.75 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 | 3,815,095 | |
| -1 | 3,815,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 83 | 145 | 317 | 415 | 1,585 | 2,407 | 9,193 | 12,035 | 26,311 | 45,965 | 131,555 | 763,019 | 3,815,095 |
| -1 | -5 | -29 | -83 | -145 | -317 | -415 | -1,585 | -2,407 | -9,193 | -12,035 | -26,311 | -45,965 | -131,555 | -763,019 | -3,815,095 |
