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 28,530,773, 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 | 28,530,773 | |
-1 | -28,530,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,530,773.
Example:
1 x 28,530,773 = 28,530,773
and
-1 x -28,530,773 = 28,530,773
Notice both answers equal 28,530,773
With that explanation out of the way, let's continue. Next, we take the number 28,530,773 and divide it by 2:
28,530,773 ÷ 2 = 14,265,386.5
If the quotient is a whole number, then 2 and 14,265,386.5 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 | 28,530,773 | |
-1 | -28,530,773 |
Now, we try dividing 28,530,773 by 3:
28,530,773 ÷ 3 = 9,510,257.6667
If the quotient is a whole number, then 3 and 9,510,257.6667 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 | 28,530,773 | |
-1 | -28,530,773 |
Let's try dividing by 4:
28,530,773 ÷ 4 = 7,132,693.25
If the quotient is a whole number, then 4 and 7,132,693.25 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 | 28,530,773 | |
-1 | 28,530,773 |
If you did it right, you will end up with this table:
1 | 281 | 101,533 | 28,530,773 |
-1 | -281 | -101,533 | -28,530,773 |
