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 63,175, 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 | 63,175 | |
| -1 | -63,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,175.
Example:
1 x 63,175 = 63,175
and
-1 x -63,175 = 63,175
Notice both answers equal 63,175
With that explanation out of the way, let's continue. Next, we take the number 63,175 and divide it by 2:
63,175 ÷ 2 = 31,587.5
If the quotient is a whole number, then 2 and 31,587.5 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 | 63,175 | |
| -1 | -63,175 |
Now, we try dividing 63,175 by 3:
63,175 ÷ 3 = 21,058.3333
If the quotient is a whole number, then 3 and 21,058.3333 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 | 63,175 | |
| -1 | -63,175 |
Let's try dividing by 4:
63,175 ÷ 4 = 15,793.75
If the quotient is a whole number, then 4 and 15,793.75 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 | 63,175 | |
| -1 | 63,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 361 | 475 | 665 | 1,805 | 2,527 | 3,325 | 9,025 | 12,635 | 63,175 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -361 | -475 | -665 | -1,805 | -2,527 | -3,325 | -9,025 | -12,635 | -63,175 |
