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 64,010,039, 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 | 64,010,039 | |
-1 | -64,010,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,010,039.
Example:
1 x 64,010,039 = 64,010,039
and
-1 x -64,010,039 = 64,010,039
Notice both answers equal 64,010,039
With that explanation out of the way, let's continue. Next, we take the number 64,010,039 and divide it by 2:
64,010,039 ÷ 2 = 32,005,019.5
If the quotient is a whole number, then 2 and 32,005,019.5 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 | 64,010,039 | |
-1 | -64,010,039 |
Now, we try dividing 64,010,039 by 3:
64,010,039 ÷ 3 = 21,336,679.6667
If the quotient is a whole number, then 3 and 21,336,679.6667 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 | 64,010,039 | |
-1 | -64,010,039 |
Let's try dividing by 4:
64,010,039 ÷ 4 = 16,002,509.75
If the quotient is a whole number, then 4 and 16,002,509.75 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 | 64,010,039 | |
-1 | 64,010,039 |
If you did it right, you will end up with this table:
1 | 1,973 | 32,443 | 64,010,039 |
-1 | -1,973 | -32,443 | -64,010,039 |
