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 47,351,185, 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 | 47,351,185 | |
| -1 | -47,351,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,351,185.
Example:
1 x 47,351,185 = 47,351,185
and
-1 x -47,351,185 = 47,351,185
Notice both answers equal 47,351,185
With that explanation out of the way, let's continue. Next, we take the number 47,351,185 and divide it by 2:
47,351,185 ÷ 2 = 23,675,592.5
If the quotient is a whole number, then 2 and 23,675,592.5 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 | 47,351,185 | |
| -1 | -47,351,185 |
Now, we try dividing 47,351,185 by 3:
47,351,185 ÷ 3 = 15,783,728.3333
If the quotient is a whole number, then 3 and 15,783,728.3333 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 | 47,351,185 | |
| -1 | -47,351,185 |
Let's try dividing by 4:
47,351,185 ÷ 4 = 11,837,796.25
If the quotient is a whole number, then 4 and 11,837,796.25 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 | 47,351,185 | |
| -1 | 47,351,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 613 | 2,207 | 3,065 | 4,291 | 11,035 | 15,449 | 21,455 | 77,245 | 1,352,891 | 6,764,455 | 9,470,237 | 47,351,185 |
| -1 | -5 | -7 | -35 | -613 | -2,207 | -3,065 | -4,291 | -11,035 | -15,449 | -21,455 | -77,245 | -1,352,891 | -6,764,455 | -9,470,237 | -47,351,185 |
