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 5,428,625, 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 | 5,428,625 | |
| -1 | -5,428,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,428,625.
Example:
1 x 5,428,625 = 5,428,625
and
-1 x -5,428,625 = 5,428,625
Notice both answers equal 5,428,625
With that explanation out of the way, let's continue. Next, we take the number 5,428,625 and divide it by 2:
5,428,625 ÷ 2 = 2,714,312.5
If the quotient is a whole number, then 2 and 2,714,312.5 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 | 5,428,625 | |
| -1 | -5,428,625 |
Now, we try dividing 5,428,625 by 3:
5,428,625 ÷ 3 = 1,809,541.6667
If the quotient is a whole number, then 3 and 1,809,541.6667 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 | 5,428,625 | |
| -1 | -5,428,625 |
Let's try dividing by 4:
5,428,625 ÷ 4 = 1,357,156.25
If the quotient is a whole number, then 4 and 1,357,156.25 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 | 5,428,625 | |
| -1 | 5,428,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 137 | 317 | 685 | 1,585 | 3,425 | 7,925 | 17,125 | 39,625 | 43,429 | 217,145 | 1,085,725 | 5,428,625 |
| -1 | -5 | -25 | -125 | -137 | -317 | -685 | -1,585 | -3,425 | -7,925 | -17,125 | -39,625 | -43,429 | -217,145 | -1,085,725 | -5,428,625 |
