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 47,581,607, 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 | 47,581,607 | |
| -1 | -47,581,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,581,607.
Example:
1 x 47,581,607 = 47,581,607
and
-1 x -47,581,607 = 47,581,607
Notice both answers equal 47,581,607
With that explanation out of the way, let's continue. Next, we take the number 47,581,607 and divide it by 2:
47,581,607 ÷ 2 = 23,790,803.5
If the quotient is a whole number, then 2 and 23,790,803.5 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 | 47,581,607 | |
| -1 | -47,581,607 |
Now, we try dividing 47,581,607 by 3:
47,581,607 ÷ 3 = 15,860,535.6667
If the quotient is a whole number, then 3 and 15,860,535.6667 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 | 47,581,607 | |
| -1 | -47,581,607 |
Let's try dividing by 4:
47,581,607 ÷ 4 = 11,895,401.75
If the quotient is a whole number, then 4 and 11,895,401.75 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 | 47,581,607 | |
| -1 | 47,581,607 |
If you did it right, you will end up with this table:
| 1 | 41 | 43 | 137 | 197 | 1,763 | 5,617 | 5,891 | 8,077 | 8,471 | 26,989 | 241,531 | 347,311 | 1,106,549 | 1,160,527 | 47,581,607 |
| -1 | -41 | -43 | -137 | -197 | -1,763 | -5,617 | -5,891 | -8,077 | -8,471 | -26,989 | -241,531 | -347,311 | -1,106,549 | -1,160,527 | -47,581,607 |
