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 102,022,661, 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 | 102,022,661 | |
| -1 | -102,022,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,022,661.
Example:
1 x 102,022,661 = 102,022,661
and
-1 x -102,022,661 = 102,022,661
Notice both answers equal 102,022,661
With that explanation out of the way, let's continue. Next, we take the number 102,022,661 and divide it by 2:
102,022,661 ÷ 2 = 51,011,330.5
If the quotient is a whole number, then 2 and 51,011,330.5 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 | 102,022,661 | |
| -1 | -102,022,661 |
Now, we try dividing 102,022,661 by 3:
102,022,661 ÷ 3 = 34,007,553.6667
If the quotient is a whole number, then 3 and 34,007,553.6667 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 | 102,022,661 | |
| -1 | -102,022,661 |
Let's try dividing by 4:
102,022,661 ÷ 4 = 25,505,665.25
If the quotient is a whole number, then 4 and 25,505,665.25 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 | 102,022,661 | |
| -1 | 102,022,661 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 179 | 221 | 2,327 | 2,579 | 3,043 | 33,527 | 39,559 | 43,843 | 461,641 | 569,959 | 6,001,333 | 7,847,897 | 102,022,661 |
| -1 | -13 | -17 | -179 | -221 | -2,327 | -2,579 | -3,043 | -33,527 | -39,559 | -43,843 | -461,641 | -569,959 | -6,001,333 | -7,847,897 | -102,022,661 |
