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 103,032,125, 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 | 103,032,125 | |
| -1 | -103,032,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,032,125.
Example:
1 x 103,032,125 = 103,032,125
and
-1 x -103,032,125 = 103,032,125
Notice both answers equal 103,032,125
With that explanation out of the way, let's continue. Next, we take the number 103,032,125 and divide it by 2:
103,032,125 ÷ 2 = 51,516,062.5
If the quotient is a whole number, then 2 and 51,516,062.5 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 | 103,032,125 | |
| -1 | -103,032,125 |
Now, we try dividing 103,032,125 by 3:
103,032,125 ÷ 3 = 34,344,041.6667
If the quotient is a whole number, then 3 and 34,344,041.6667 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 | 103,032,125 | |
| -1 | -103,032,125 |
Let's try dividing by 4:
103,032,125 ÷ 4 = 25,758,031.25
If the quotient is a whole number, then 4 and 25,758,031.25 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 | 103,032,125 | |
| -1 | 103,032,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 117,751 | 588,755 | 824,257 | 2,943,775 | 4,121,285 | 14,718,875 | 20,606,425 | 103,032,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -117,751 | -588,755 | -824,257 | -2,943,775 | -4,121,285 | -14,718,875 | -20,606,425 | -103,032,125 |
