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 3,815,675, 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 | 3,815,675 | |
| -1 | -3,815,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,815,675.
Example:
1 x 3,815,675 = 3,815,675
and
-1 x -3,815,675 = 3,815,675
Notice both answers equal 3,815,675
With that explanation out of the way, let's continue. Next, we take the number 3,815,675 and divide it by 2:
3,815,675 ÷ 2 = 1,907,837.5
If the quotient is a whole number, then 2 and 1,907,837.5 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 | 3,815,675 | |
| -1 | -3,815,675 |
Now, we try dividing 3,815,675 by 3:
3,815,675 ÷ 3 = 1,271,891.6667
If the quotient is a whole number, then 3 and 1,271,891.6667 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 | 3,815,675 | |
| -1 | -3,815,675 |
Let's try dividing by 4:
3,815,675 ÷ 4 = 953,918.75
If the quotient is a whole number, then 4 and 953,918.75 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 | 3,815,675 | |
| -1 | 3,815,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 29 | 95 | 145 | 277 | 475 | 551 | 725 | 1,385 | 2,755 | 5,263 | 6,925 | 8,033 | 13,775 | 26,315 | 40,165 | 131,575 | 152,627 | 200,825 | 763,135 | 3,815,675 |
| -1 | -5 | -19 | -25 | -29 | -95 | -145 | -277 | -475 | -551 | -725 | -1,385 | -2,755 | -5,263 | -6,925 | -8,033 | -13,775 | -26,315 | -40,165 | -131,575 | -152,627 | -200,825 | -763,135 | -3,815,675 |
