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 520,975, 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 | 520,975 | |
| -1 | -520,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,975.
Example:
1 x 520,975 = 520,975
and
-1 x -520,975 = 520,975
Notice both answers equal 520,975
With that explanation out of the way, let's continue. Next, we take the number 520,975 and divide it by 2:
520,975 ÷ 2 = 260,487.5
If the quotient is a whole number, then 2 and 260,487.5 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 | 520,975 | |
| -1 | -520,975 |
Now, we try dividing 520,975 by 3:
520,975 ÷ 3 = 173,658.3333
If the quotient is a whole number, then 3 and 173,658.3333 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 | 520,975 | |
| -1 | -520,975 |
Let's try dividing by 4:
520,975 ÷ 4 = 130,243.75
If the quotient is a whole number, then 4 and 130,243.75 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 | 520,975 | |
| -1 | 520,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 229 | 325 | 455 | 1,145 | 1,603 | 2,275 | 2,977 | 5,725 | 8,015 | 14,885 | 20,839 | 40,075 | 74,425 | 104,195 | 520,975 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -229 | -325 | -455 | -1,145 | -1,603 | -2,275 | -2,977 | -5,725 | -8,015 | -14,885 | -20,839 | -40,075 | -74,425 | -104,195 | -520,975 |
