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 2,715,835, 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 | 2,715,835 | |
| -1 | -2,715,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,715,835.
Example:
1 x 2,715,835 = 2,715,835
and
-1 x -2,715,835 = 2,715,835
Notice both answers equal 2,715,835
With that explanation out of the way, let's continue. Next, we take the number 2,715,835 and divide it by 2:
2,715,835 ÷ 2 = 1,357,917.5
If the quotient is a whole number, then 2 and 1,357,917.5 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 | 2,715,835 | |
| -1 | -2,715,835 |
Now, we try dividing 2,715,835 by 3:
2,715,835 ÷ 3 = 905,278.3333
If the quotient is a whole number, then 3 and 905,278.3333 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 | 2,715,835 | |
| -1 | -2,715,835 |
Let's try dividing by 4:
2,715,835 ÷ 4 = 678,958.75
If the quotient is a whole number, then 4 and 678,958.75 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 | 2,715,835 | |
| -1 | 2,715,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 89 | 359 | 445 | 1,513 | 1,795 | 6,103 | 7,565 | 30,515 | 31,951 | 159,755 | 543,167 | 2,715,835 |
| -1 | -5 | -17 | -85 | -89 | -359 | -445 | -1,513 | -1,795 | -6,103 | -7,565 | -30,515 | -31,951 | -159,755 | -543,167 | -2,715,835 |
