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 63,175,145, 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 | 63,175,145 | |
| -1 | -63,175,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,175,145.
Example:
1 x 63,175,145 = 63,175,145
and
-1 x -63,175,145 = 63,175,145
Notice both answers equal 63,175,145
With that explanation out of the way, let's continue. Next, we take the number 63,175,145 and divide it by 2:
63,175,145 ÷ 2 = 31,587,572.5
If the quotient is a whole number, then 2 and 31,587,572.5 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 | 63,175,145 | |
| -1 | -63,175,145 |
Now, we try dividing 63,175,145 by 3:
63,175,145 ÷ 3 = 21,058,381.6667
If the quotient is a whole number, then 3 and 21,058,381.6667 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 | 63,175,145 | |
| -1 | -63,175,145 |
Let's try dividing by 4:
63,175,145 ÷ 4 = 15,793,786.25
If the quotient is a whole number, then 4 and 15,793,786.25 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 | 63,175,145 | |
| -1 | 63,175,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 67,567 | 337,835 | 743,237 | 1,148,639 | 3,716,185 | 5,743,195 | 12,635,029 | 63,175,145 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -67,567 | -337,835 | -743,237 | -1,148,639 | -3,716,185 | -5,743,195 | -12,635,029 | -63,175,145 |
