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 47,421,485, 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 | 47,421,485 | |
| -1 | -47,421,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,421,485.
Example:
1 x 47,421,485 = 47,421,485
and
-1 x -47,421,485 = 47,421,485
Notice both answers equal 47,421,485
With that explanation out of the way, let's continue. Next, we take the number 47,421,485 and divide it by 2:
47,421,485 ÷ 2 = 23,710,742.5
If the quotient is a whole number, then 2 and 23,710,742.5 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 | 47,421,485 | |
| -1 | -47,421,485 |
Now, we try dividing 47,421,485 by 3:
47,421,485 ÷ 3 = 15,807,161.6667
If the quotient is a whole number, then 3 and 15,807,161.6667 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 | 47,421,485 | |
| -1 | -47,421,485 |
Let's try dividing by 4:
47,421,485 ÷ 4 = 11,855,371.25
If the quotient is a whole number, then 4 and 11,855,371.25 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 | 47,421,485 | |
| -1 | 47,421,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 149 | 265 | 745 | 1,201 | 6,005 | 7,897 | 39,485 | 63,653 | 178,949 | 318,265 | 894,745 | 9,484,297 | 47,421,485 |
| -1 | -5 | -53 | -149 | -265 | -745 | -1,201 | -6,005 | -7,897 | -39,485 | -63,653 | -178,949 | -318,265 | -894,745 | -9,484,297 | -47,421,485 |
