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 47,788,481, 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 | 47,788,481 | |
-1 | -47,788,481 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,788,481.
Example:
1 x 47,788,481 = 47,788,481
and
-1 x -47,788,481 = 47,788,481
Notice both answers equal 47,788,481
With that explanation out of the way, let's continue. Next, we take the number 47,788,481 and divide it by 2:
47,788,481 ÷ 2 = 23,894,240.5
If the quotient is a whole number, then 2 and 23,894,240.5 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 | 47,788,481 | |
-1 | -47,788,481 |
Now, we try dividing 47,788,481 by 3:
47,788,481 ÷ 3 = 15,929,493.6667
If the quotient is a whole number, then 3 and 15,929,493.6667 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 | 47,788,481 | |
-1 | -47,788,481 |
Let's try dividing by 4:
47,788,481 ÷ 4 = 11,947,120.25
If the quotient is a whole number, then 4 and 11,947,120.25 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 | 47,788,481 | |
-1 | 47,788,481 |
If you did it right, you will end up with this table:
1 | 13 | 3,676,037 | 47,788,481 |
-1 | -13 | -3,676,037 | -47,788,481 |
