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 427,975, 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 | 427,975 | |
| -1 | -427,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 427,975.
Example:
1 x 427,975 = 427,975
and
-1 x -427,975 = 427,975
Notice both answers equal 427,975
With that explanation out of the way, let's continue. Next, we take the number 427,975 and divide it by 2:
427,975 ÷ 2 = 213,987.5
If the quotient is a whole number, then 2 and 213,987.5 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 | 427,975 | |
| -1 | -427,975 |
Now, we try dividing 427,975 by 3:
427,975 ÷ 3 = 142,658.3333
If the quotient is a whole number, then 3 and 142,658.3333 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 | 427,975 | |
| -1 | -427,975 |
Let's try dividing by 4:
427,975 ÷ 4 = 106,993.75
If the quotient is a whole number, then 4 and 106,993.75 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 | 427,975 | |
| -1 | 427,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 25 | 53 | 85 | 95 | 265 | 323 | 425 | 475 | 901 | 1,007 | 1,325 | 1,615 | 4,505 | 5,035 | 8,075 | 17,119 | 22,525 | 25,175 | 85,595 | 427,975 |
| -1 | -5 | -17 | -19 | -25 | -53 | -85 | -95 | -265 | -323 | -425 | -475 | -901 | -1,007 | -1,325 | -1,615 | -4,505 | -5,035 | -8,075 | -17,119 | -22,525 | -25,175 | -85,595 | -427,975 |
