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 258,305,477, 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 | 258,305,477 | |
-1 | -258,305,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 258,305,477.
Example:
1 x 258,305,477 = 258,305,477
and
-1 x -258,305,477 = 258,305,477
Notice both answers equal 258,305,477
With that explanation out of the way, let's continue. Next, we take the number 258,305,477 and divide it by 2:
258,305,477 ÷ 2 = 129,152,738.5
If the quotient is a whole number, then 2 and 129,152,738.5 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 | 258,305,477 | |
-1 | -258,305,477 |
Now, we try dividing 258,305,477 by 3:
258,305,477 ÷ 3 = 86,101,825.6667
If the quotient is a whole number, then 3 and 86,101,825.6667 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 | 258,305,477 | |
-1 | -258,305,477 |
Let's try dividing by 4:
258,305,477 ÷ 4 = 64,576,369.25
If the quotient is a whole number, then 4 and 64,576,369.25 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 | 258,305,477 | |
-1 | 258,305,477 |
If you did it right, you will end up with this table:
1 | 6,329 | 40,813 | 258,305,477 |
-1 | -6,329 | -40,813 | -258,305,477 |
