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 47,606,845, 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 | 47,606,845 | |
| -1 | -47,606,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,606,845.
Example:
1 x 47,606,845 = 47,606,845
and
-1 x -47,606,845 = 47,606,845
Notice both answers equal 47,606,845
With that explanation out of the way, let's continue. Next, we take the number 47,606,845 and divide it by 2:
47,606,845 ÷ 2 = 23,803,422.5
If the quotient is a whole number, then 2 and 23,803,422.5 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 | 47,606,845 | |
| -1 | -47,606,845 |
Now, we try dividing 47,606,845 by 3:
47,606,845 ÷ 3 = 15,868,948.3333
If the quotient is a whole number, then 3 and 15,868,948.3333 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 | 47,606,845 | |
| -1 | -47,606,845 |
Let's try dividing by 4:
47,606,845 ÷ 4 = 11,901,711.25
If the quotient is a whole number, then 4 and 11,901,711.25 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 | 47,606,845 | |
| -1 | 47,606,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 121 | 143 | 605 | 715 | 1,573 | 6,053 | 7,865 | 30,265 | 66,583 | 78,689 | 332,915 | 393,445 | 732,413 | 865,579 | 3,662,065 | 4,327,895 | 9,521,369 | 47,606,845 |
| -1 | -5 | -11 | -13 | -55 | -65 | -121 | -143 | -605 | -715 | -1,573 | -6,053 | -7,865 | -30,265 | -66,583 | -78,689 | -332,915 | -393,445 | -732,413 | -865,579 | -3,662,065 | -4,327,895 | -9,521,369 | -47,606,845 |
