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 137,185,325, 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 | 137,185,325 | |
| -1 | -137,185,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,185,325.
Example:
1 x 137,185,325 = 137,185,325
and
-1 x -137,185,325 = 137,185,325
Notice both answers equal 137,185,325
With that explanation out of the way, let's continue. Next, we take the number 137,185,325 and divide it by 2:
137,185,325 ÷ 2 = 68,592,662.5
If the quotient is a whole number, then 2 and 68,592,662.5 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 | 137,185,325 | |
| -1 | -137,185,325 |
Now, we try dividing 137,185,325 by 3:
137,185,325 ÷ 3 = 45,728,441.6667
If the quotient is a whole number, then 3 and 45,728,441.6667 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 | 137,185,325 | |
| -1 | -137,185,325 |
Let's try dividing by 4:
137,185,325 ÷ 4 = 34,296,331.25
If the quotient is a whole number, then 4 and 34,296,331.25 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 | 137,185,325 | |
| -1 | 137,185,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 59 | 85 | 295 | 425 | 1,003 | 1,475 | 5,015 | 5,471 | 25,075 | 27,355 | 93,007 | 136,775 | 322,789 | 465,035 | 1,613,945 | 2,325,175 | 5,487,413 | 8,069,725 | 27,437,065 | 137,185,325 |
| -1 | -5 | -17 | -25 | -59 | -85 | -295 | -425 | -1,003 | -1,475 | -5,015 | -5,471 | -25,075 | -27,355 | -93,007 | -136,775 | -322,789 | -465,035 | -1,613,945 | -2,325,175 | -5,487,413 | -8,069,725 | -27,437,065 | -137,185,325 |
