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 168,260,251, 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 | 168,260,251 | |
-1 | -168,260,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 168,260,251.
Example:
1 x 168,260,251 = 168,260,251
and
-1 x -168,260,251 = 168,260,251
Notice both answers equal 168,260,251
With that explanation out of the way, let's continue. Next, we take the number 168,260,251 and divide it by 2:
168,260,251 ÷ 2 = 84,130,125.5
If the quotient is a whole number, then 2 and 84,130,125.5 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 | 168,260,251 | |
-1 | -168,260,251 |
Now, we try dividing 168,260,251 by 3:
168,260,251 ÷ 3 = 56,086,750.3333
If the quotient is a whole number, then 3 and 56,086,750.3333 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 | 168,260,251 | |
-1 | -168,260,251 |
Let's try dividing by 4:
168,260,251 ÷ 4 = 42,065,062.75
If the quotient is a whole number, then 4 and 42,065,062.75 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 | 168,260,251 | |
-1 | 168,260,251 |
If you did it right, you will end up with this table:
1 | 233 | 722,147 | 168,260,251 |
-1 | -233 | -722,147 | -168,260,251 |
