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 171,015,635, 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 | 171,015,635 | |
| -1 | -171,015,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,015,635.
Example:
1 x 171,015,635 = 171,015,635
and
-1 x -171,015,635 = 171,015,635
Notice both answers equal 171,015,635
With that explanation out of the way, let's continue. Next, we take the number 171,015,635 and divide it by 2:
171,015,635 ÷ 2 = 85,507,817.5
If the quotient is a whole number, then 2 and 85,507,817.5 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 | 171,015,635 | |
| -1 | -171,015,635 |
Now, we try dividing 171,015,635 by 3:
171,015,635 ÷ 3 = 57,005,211.6667
If the quotient is a whole number, then 3 and 57,005,211.6667 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 | 171,015,635 | |
| -1 | -171,015,635 |
Let's try dividing by 4:
171,015,635 ÷ 4 = 42,753,908.75
If the quotient is a whole number, then 4 and 42,753,908.75 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 | 171,015,635 | |
| -1 | 171,015,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 61 | 245 | 305 | 427 | 2,135 | 2,989 | 11,443 | 14,945 | 57,215 | 80,101 | 400,505 | 560,707 | 698,023 | 2,803,535 | 3,490,115 | 4,886,161 | 24,430,805 | 34,203,127 | 171,015,635 |
| -1 | -5 | -7 | -35 | -49 | -61 | -245 | -305 | -427 | -2,135 | -2,989 | -11,443 | -14,945 | -57,215 | -80,101 | -400,505 | -560,707 | -698,023 | -2,803,535 | -3,490,115 | -4,886,161 | -24,430,805 | -34,203,127 | -171,015,635 |
