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 6,647,525, 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 | 6,647,525 | |
| -1 | -6,647,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,647,525.
Example:
1 x 6,647,525 = 6,647,525
and
-1 x -6,647,525 = 6,647,525
Notice both answers equal 6,647,525
With that explanation out of the way, let's continue. Next, we take the number 6,647,525 and divide it by 2:
6,647,525 ÷ 2 = 3,323,762.5
If the quotient is a whole number, then 2 and 3,323,762.5 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 | 6,647,525 | |
| -1 | -6,647,525 |
Now, we try dividing 6,647,525 by 3:
6,647,525 ÷ 3 = 2,215,841.6667
If the quotient is a whole number, then 3 and 2,215,841.6667 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 | 6,647,525 | |
| -1 | -6,647,525 |
Let's try dividing by 4:
6,647,525 ÷ 4 = 1,661,881.25
If the quotient is a whole number, then 4 and 1,661,881.25 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 | 6,647,525 | |
| -1 | 6,647,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 53 | 145 | 173 | 265 | 725 | 865 | 1,325 | 1,537 | 4,325 | 5,017 | 7,685 | 9,169 | 25,085 | 38,425 | 45,845 | 125,425 | 229,225 | 265,901 | 1,329,505 | 6,647,525 |
| -1 | -5 | -25 | -29 | -53 | -145 | -173 | -265 | -725 | -865 | -1,325 | -1,537 | -4,325 | -5,017 | -7,685 | -9,169 | -25,085 | -38,425 | -45,845 | -125,425 | -229,225 | -265,901 | -1,329,505 | -6,647,525 |
