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 4,821,025, 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 | 4,821,025 | |
| -1 | -4,821,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,821,025.
Example:
1 x 4,821,025 = 4,821,025
and
-1 x -4,821,025 = 4,821,025
Notice both answers equal 4,821,025
With that explanation out of the way, let's continue. Next, we take the number 4,821,025 and divide it by 2:
4,821,025 ÷ 2 = 2,410,512.5
If the quotient is a whole number, then 2 and 2,410,512.5 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 | 4,821,025 | |
| -1 | -4,821,025 |
Now, we try dividing 4,821,025 by 3:
4,821,025 ÷ 3 = 1,607,008.3333
If the quotient is a whole number, then 3 and 1,607,008.3333 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 | 4,821,025 | |
| -1 | -4,821,025 |
Let's try dividing by 4:
4,821,025 ÷ 4 = 1,205,256.25
If the quotient is a whole number, then 4 and 1,205,256.25 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 | 4,821,025 | |
| -1 | 4,821,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 47 | 55 | 235 | 275 | 373 | 517 | 1,175 | 1,865 | 2,585 | 4,103 | 9,325 | 12,925 | 17,531 | 20,515 | 87,655 | 102,575 | 192,841 | 438,275 | 964,205 | 4,821,025 |
| -1 | -5 | -11 | -25 | -47 | -55 | -235 | -275 | -373 | -517 | -1,175 | -1,865 | -2,585 | -4,103 | -9,325 | -12,925 | -17,531 | -20,515 | -87,655 | -102,575 | -192,841 | -438,275 | -964,205 | -4,821,025 |
