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 6,451,025, 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 | 6,451,025 | |
| -1 | -6,451,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,451,025.
Example:
1 x 6,451,025 = 6,451,025
and
-1 x -6,451,025 = 6,451,025
Notice both answers equal 6,451,025
With that explanation out of the way, let's continue. Next, we take the number 6,451,025 and divide it by 2:
6,451,025 ÷ 2 = 3,225,512.5
If the quotient is a whole number, then 2 and 3,225,512.5 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 | 6,451,025 | |
| -1 | -6,451,025 |
Now, we try dividing 6,451,025 by 3:
6,451,025 ÷ 3 = 2,150,341.6667
If the quotient is a whole number, then 3 and 2,150,341.6667 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 | 6,451,025 | |
| -1 | -6,451,025 |
Let's try dividing by 4:
6,451,025 ÷ 4 = 1,612,756.25
If the quotient is a whole number, then 4 and 1,612,756.25 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 | 6,451,025 | |
| -1 | 6,451,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 191 | 193 | 955 | 965 | 1,337 | 1,351 | 4,775 | 4,825 | 6,685 | 6,755 | 33,425 | 33,775 | 36,863 | 184,315 | 258,041 | 921,575 | 1,290,205 | 6,451,025 |
| -1 | -5 | -7 | -25 | -35 | -175 | -191 | -193 | -955 | -965 | -1,337 | -1,351 | -4,775 | -4,825 | -6,685 | -6,755 | -33,425 | -33,775 | -36,863 | -184,315 | -258,041 | -921,575 | -1,290,205 | -6,451,025 |
