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 47,321,599, 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 | 47,321,599 | |
| -1 | -47,321,599 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,321,599.
Example:
1 x 47,321,599 = 47,321,599
and
-1 x -47,321,599 = 47,321,599
Notice both answers equal 47,321,599
With that explanation out of the way, let's continue. Next, we take the number 47,321,599 and divide it by 2:
47,321,599 ÷ 2 = 23,660,799.5
If the quotient is a whole number, then 2 and 23,660,799.5 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 | 47,321,599 | |
| -1 | -47,321,599 |
Now, we try dividing 47,321,599 by 3:
47,321,599 ÷ 3 = 15,773,866.3333
If the quotient is a whole number, then 3 and 15,773,866.3333 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 | 47,321,599 | |
| -1 | -47,321,599 |
Let's try dividing by 4:
47,321,599 ÷ 4 = 11,830,399.75
If the quotient is a whole number, then 4 and 11,830,399.75 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 | 47,321,599 | |
| -1 | 47,321,599 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 103 | 599 | 767 | 1,339 | 6,077 | 7,787 | 35,341 | 61,697 | 79,001 | 459,433 | 802,061 | 3,640,123 | 47,321,599 |
| -1 | -13 | -59 | -103 | -599 | -767 | -1,339 | -6,077 | -7,787 | -35,341 | -61,697 | -79,001 | -459,433 | -802,061 | -3,640,123 | -47,321,599 |
