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 160,101,125, 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 | 160,101,125 | |
| -1 | -160,101,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,101,125.
Example:
1 x 160,101,125 = 160,101,125
and
-1 x -160,101,125 = 160,101,125
Notice both answers equal 160,101,125
With that explanation out of the way, let's continue. Next, we take the number 160,101,125 and divide it by 2:
160,101,125 ÷ 2 = 80,050,562.5
If the quotient is a whole number, then 2 and 80,050,562.5 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 | 160,101,125 | |
| -1 | -160,101,125 |
Now, we try dividing 160,101,125 by 3:
160,101,125 ÷ 3 = 53,367,041.6667
If the quotient is a whole number, then 3 and 53,367,041.6667 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 | 160,101,125 | |
| -1 | -160,101,125 |
Let's try dividing by 4:
160,101,125 ÷ 4 = 40,025,281.25
If the quotient is a whole number, then 4 and 40,025,281.25 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 | 160,101,125 | |
| -1 | 160,101,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 125 | 475 | 2,375 | 67,411 | 337,055 | 1,280,809 | 1,685,275 | 6,404,045 | 8,426,375 | 32,020,225 | 160,101,125 |
| -1 | -5 | -19 | -25 | -95 | -125 | -475 | -2,375 | -67,411 | -337,055 | -1,280,809 | -1,685,275 | -6,404,045 | -8,426,375 | -32,020,225 | -160,101,125 |
