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 47,307,155, 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 | 47,307,155 | |
| -1 | -47,307,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,307,155.
Example:
1 x 47,307,155 = 47,307,155
and
-1 x -47,307,155 = 47,307,155
Notice both answers equal 47,307,155
With that explanation out of the way, let's continue. Next, we take the number 47,307,155 and divide it by 2:
47,307,155 ÷ 2 = 23,653,577.5
If the quotient is a whole number, then 2 and 23,653,577.5 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 | 47,307,155 | |
| -1 | -47,307,155 |
Now, we try dividing 47,307,155 by 3:
47,307,155 ÷ 3 = 15,769,051.6667
If the quotient is a whole number, then 3 and 15,769,051.6667 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 | 47,307,155 | |
| -1 | -47,307,155 |
Let's try dividing by 4:
47,307,155 ÷ 4 = 11,826,788.75
If the quotient is a whole number, then 4 and 11,826,788.75 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 | 47,307,155 | |
| -1 | 47,307,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 233 | 1,165 | 1,631 | 5,801 | 8,155 | 29,005 | 40,607 | 203,035 | 1,351,633 | 6,758,165 | 9,461,431 | 47,307,155 |
| -1 | -5 | -7 | -35 | -233 | -1,165 | -1,631 | -5,801 | -8,155 | -29,005 | -40,607 | -203,035 | -1,351,633 | -6,758,165 | -9,461,431 | -47,307,155 |
