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 2,647,615, 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 | 2,647,615 | |
| -1 | -2,647,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,647,615.
Example:
1 x 2,647,615 = 2,647,615
and
-1 x -2,647,615 = 2,647,615
Notice both answers equal 2,647,615
With that explanation out of the way, let's continue. Next, we take the number 2,647,615 and divide it by 2:
2,647,615 ÷ 2 = 1,323,807.5
If the quotient is a whole number, then 2 and 1,323,807.5 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 | 2,647,615 | |
| -1 | -2,647,615 |
Now, we try dividing 2,647,615 by 3:
2,647,615 ÷ 3 = 882,538.3333
If the quotient is a whole number, then 3 and 882,538.3333 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 | 2,647,615 | |
| -1 | -2,647,615 |
Let's try dividing by 4:
2,647,615 ÷ 4 = 661,903.75
If the quotient is a whole number, then 4 and 661,903.75 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 | 2,647,615 | |
| -1 | 2,647,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 97 | 103 | 265 | 485 | 515 | 5,141 | 5,459 | 9,991 | 25,705 | 27,295 | 49,955 | 529,523 | 2,647,615 |
| -1 | -5 | -53 | -97 | -103 | -265 | -485 | -515 | -5,141 | -5,459 | -9,991 | -25,705 | -27,295 | -49,955 | -529,523 | -2,647,615 |
