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 6,544,525, 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 | 6,544,525 | |
| -1 | -6,544,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,544,525.
Example:
1 x 6,544,525 = 6,544,525
and
-1 x -6,544,525 = 6,544,525
Notice both answers equal 6,544,525
With that explanation out of the way, let's continue. Next, we take the number 6,544,525 and divide it by 2:
6,544,525 ÷ 2 = 3,272,262.5
If the quotient is a whole number, then 2 and 3,272,262.5 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 | 6,544,525 | |
| -1 | -6,544,525 |
Now, we try dividing 6,544,525 by 3:
6,544,525 ÷ 3 = 2,181,508.3333
If the quotient is a whole number, then 3 and 2,181,508.3333 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 | 6,544,525 | |
| -1 | -6,544,525 |
Let's try dividing by 4:
6,544,525 ÷ 4 = 1,636,131.25
If the quotient is a whole number, then 4 and 1,636,131.25 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 | 6,544,525 | |
| -1 | 6,544,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 169 | 325 | 845 | 1,549 | 4,225 | 7,745 | 20,137 | 38,725 | 100,685 | 261,781 | 503,425 | 1,308,905 | 6,544,525 |
| -1 | -5 | -13 | -25 | -65 | -169 | -325 | -845 | -1,549 | -4,225 | -7,745 | -20,137 | -38,725 | -100,685 | -261,781 | -503,425 | -1,308,905 | -6,544,525 |
