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 47,977,915, 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 | 47,977,915 | |
| -1 | -47,977,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,977,915.
Example:
1 x 47,977,915 = 47,977,915
and
-1 x -47,977,915 = 47,977,915
Notice both answers equal 47,977,915
With that explanation out of the way, let's continue. Next, we take the number 47,977,915 and divide it by 2:
47,977,915 ÷ 2 = 23,988,957.5
If the quotient is a whole number, then 2 and 23,988,957.5 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 | 47,977,915 | |
| -1 | -47,977,915 |
Now, we try dividing 47,977,915 by 3:
47,977,915 ÷ 3 = 15,992,638.3333
If the quotient is a whole number, then 3 and 15,992,638.3333 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 | 47,977,915 | |
| -1 | -47,977,915 |
Let's try dividing by 4:
47,977,915 ÷ 4 = 11,994,478.75
If the quotient is a whole number, then 4 and 11,994,478.75 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 | 47,977,915 | |
| -1 | 47,977,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 103 | 295 | 515 | 1,579 | 6,077 | 7,895 | 30,385 | 93,161 | 162,637 | 465,805 | 813,185 | 9,595,583 | 47,977,915 |
| -1 | -5 | -59 | -103 | -295 | -515 | -1,579 | -6,077 | -7,895 | -30,385 | -93,161 | -162,637 | -465,805 | -813,185 | -9,595,583 | -47,977,915 |
