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 6,472,025, 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 | 6,472,025 | |
| -1 | -6,472,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,472,025.
Example:
1 x 6,472,025 = 6,472,025
and
-1 x -6,472,025 = 6,472,025
Notice both answers equal 6,472,025
With that explanation out of the way, let's continue. Next, we take the number 6,472,025 and divide it by 2:
6,472,025 ÷ 2 = 3,236,012.5
If the quotient is a whole number, then 2 and 3,236,012.5 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 | 6,472,025 | |
| -1 | -6,472,025 |
Now, we try dividing 6,472,025 by 3:
6,472,025 ÷ 3 = 2,157,341.6667
If the quotient is a whole number, then 3 and 2,157,341.6667 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 | 6,472,025 | |
| -1 | -6,472,025 |
Let's try dividing by 4:
6,472,025 ÷ 4 = 1,618,006.25
If the quotient is a whole number, then 4 and 1,618,006.25 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 | 6,472,025 | |
| -1 | 6,472,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 775 | 1,085 | 1,193 | 5,425 | 5,965 | 8,351 | 29,825 | 36,983 | 41,755 | 184,915 | 208,775 | 258,881 | 924,575 | 1,294,405 | 6,472,025 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -775 | -1,085 | -1,193 | -5,425 | -5,965 | -8,351 | -29,825 | -36,983 | -41,755 | -184,915 | -208,775 | -258,881 | -924,575 | -1,294,405 | -6,472,025 |
