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 171,073,747, 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 | 171,073,747 | |
| -1 | -171,073,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,073,747.
Example:
1 x 171,073,747 = 171,073,747
and
-1 x -171,073,747 = 171,073,747
Notice both answers equal 171,073,747
With that explanation out of the way, let's continue. Next, we take the number 171,073,747 and divide it by 2:
171,073,747 ÷ 2 = 85,536,873.5
If the quotient is a whole number, then 2 and 85,536,873.5 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 | 171,073,747 | |
| -1 | -171,073,747 |
Now, we try dividing 171,073,747 by 3:
171,073,747 ÷ 3 = 57,024,582.3333
If the quotient is a whole number, then 3 and 57,024,582.3333 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 | 171,073,747 | |
| -1 | -171,073,747 |
Let's try dividing by 4:
171,073,747 ÷ 4 = 42,768,436.75
If the quotient is a whole number, then 4 and 42,768,436.75 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 | 171,073,747 | |
| -1 | 171,073,747 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 367 | 1,559 | 4,771 | 8,441 | 20,267 | 35,857 | 109,733 | 466,141 | 572,153 | 7,437,989 | 13,159,519 | 171,073,747 |
| -1 | -13 | -23 | -299 | -367 | -1,559 | -4,771 | -8,441 | -20,267 | -35,857 | -109,733 | -466,141 | -572,153 | -7,437,989 | -13,159,519 | -171,073,747 |
