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 65,510,999, 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 | 65,510,999 | |
-1 | -65,510,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,510,999.
Example:
1 x 65,510,999 = 65,510,999
and
-1 x -65,510,999 = 65,510,999
Notice both answers equal 65,510,999
With that explanation out of the way, let's continue. Next, we take the number 65,510,999 and divide it by 2:
65,510,999 ÷ 2 = 32,755,499.5
If the quotient is a whole number, then 2 and 32,755,499.5 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 | 65,510,999 | |
-1 | -65,510,999 |
Now, we try dividing 65,510,999 by 3:
65,510,999 ÷ 3 = 21,836,999.6667
If the quotient is a whole number, then 3 and 21,836,999.6667 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 | 65,510,999 | |
-1 | -65,510,999 |
Let's try dividing by 4:
65,510,999 ÷ 4 = 16,377,749.75
If the quotient is a whole number, then 4 and 16,377,749.75 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 | 65,510,999 | |
-1 | 65,510,999 |
If you did it right, you will end up with this table:
1 | 199 | 329,201 | 65,510,999 |
-1 | -199 | -329,201 | -65,510,999 |
