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 547,525, 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 | 547,525 | |
| -1 | -547,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 547,525.
Example:
1 x 547,525 = 547,525
and
-1 x -547,525 = 547,525
Notice both answers equal 547,525
With that explanation out of the way, let's continue. Next, we take the number 547,525 and divide it by 2:
547,525 ÷ 2 = 273,762.5
If the quotient is a whole number, then 2 and 273,762.5 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 | 547,525 | |
| -1 | -547,525 |
Now, we try dividing 547,525 by 3:
547,525 ÷ 3 = 182,508.3333
If the quotient is a whole number, then 3 and 182,508.3333 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 | 547,525 | |
| -1 | -547,525 |
Let's try dividing by 4:
547,525 ÷ 4 = 136,881.25
If the quotient is a whole number, then 4 and 136,881.25 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 | 547,525 | |
| -1 | 547,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 181 | 275 | 605 | 905 | 1,991 | 3,025 | 4,525 | 9,955 | 21,901 | 49,775 | 109,505 | 547,525 |
| -1 | -5 | -11 | -25 | -55 | -121 | -181 | -275 | -605 | -905 | -1,991 | -3,025 | -4,525 | -9,955 | -21,901 | -49,775 | -109,505 | -547,525 |
