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 147,170,125, 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 | 147,170,125 | |
| -1 | -147,170,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,170,125.
Example:
1 x 147,170,125 = 147,170,125
and
-1 x -147,170,125 = 147,170,125
Notice both answers equal 147,170,125
With that explanation out of the way, let's continue. Next, we take the number 147,170,125 and divide it by 2:
147,170,125 ÷ 2 = 73,585,062.5
If the quotient is a whole number, then 2 and 73,585,062.5 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 | 147,170,125 | |
| -1 | -147,170,125 |
Now, we try dividing 147,170,125 by 3:
147,170,125 ÷ 3 = 49,056,708.3333
If the quotient is a whole number, then 3 and 49,056,708.3333 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 | 147,170,125 | |
| -1 | -147,170,125 |
Let's try dividing by 4:
147,170,125 ÷ 4 = 36,792,531.25
If the quotient is a whole number, then 4 and 36,792,531.25 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 | 147,170,125 | |
| -1 | 147,170,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 125 | 305 | 1,525 | 7,625 | 19,301 | 96,505 | 482,525 | 1,177,361 | 2,412,625 | 5,886,805 | 29,434,025 | 147,170,125 |
| -1 | -5 | -25 | -61 | -125 | -305 | -1,525 | -7,625 | -19,301 | -96,505 | -482,525 | -1,177,361 | -2,412,625 | -5,886,805 | -29,434,025 | -147,170,125 |
