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 171,105,575, 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 | 171,105,575 | |
| -1 | -171,105,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,105,575.
Example:
1 x 171,105,575 = 171,105,575
and
-1 x -171,105,575 = 171,105,575
Notice both answers equal 171,105,575
With that explanation out of the way, let's continue. Next, we take the number 171,105,575 and divide it by 2:
171,105,575 ÷ 2 = 85,552,787.5
If the quotient is a whole number, then 2 and 85,552,787.5 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 | 171,105,575 | |
| -1 | -171,105,575 |
Now, we try dividing 171,105,575 by 3:
171,105,575 ÷ 3 = 57,035,191.6667
If the quotient is a whole number, then 3 and 57,035,191.6667 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 | 171,105,575 | |
| -1 | -171,105,575 |
Let's try dividing by 4:
171,105,575 ÷ 4 = 42,776,393.75
If the quotient is a whole number, then 4 and 42,776,393.75 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 | 171,105,575 | |
| -1 | 171,105,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 97 | 185 | 485 | 925 | 1,907 | 2,425 | 3,589 | 9,535 | 17,945 | 47,675 | 70,559 | 89,725 | 184,979 | 352,795 | 924,895 | 1,763,975 | 4,624,475 | 6,844,223 | 34,221,115 | 171,105,575 |
| -1 | -5 | -25 | -37 | -97 | -185 | -485 | -925 | -1,907 | -2,425 | -3,589 | -9,535 | -17,945 | -47,675 | -70,559 | -89,725 | -184,979 | -352,795 | -924,895 | -1,763,975 | -4,624,475 | -6,844,223 | -34,221,115 | -171,105,575 |
