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 47,355,847, 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 | 47,355,847 | |
| -1 | -47,355,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,355,847.
Example:
1 x 47,355,847 = 47,355,847
and
-1 x -47,355,847 = 47,355,847
Notice both answers equal 47,355,847
With that explanation out of the way, let's continue. Next, we take the number 47,355,847 and divide it by 2:
47,355,847 ÷ 2 = 23,677,923.5
If the quotient is a whole number, then 2 and 23,677,923.5 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 | 47,355,847 | |
| -1 | -47,355,847 |
Now, we try dividing 47,355,847 by 3:
47,355,847 ÷ 3 = 15,785,282.3333
If the quotient is a whole number, then 3 and 15,785,282.3333 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 | 47,355,847 | |
| -1 | -47,355,847 |
Let's try dividing by 4:
47,355,847 ÷ 4 = 11,838,961.75
If the quotient is a whole number, then 4 and 11,838,961.75 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 | 47,355,847 | |
| -1 | 47,355,847 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 133 | 209 | 1,463 | 32,369 | 226,583 | 356,059 | 615,011 | 2,492,413 | 4,305,077 | 6,765,121 | 47,355,847 |
| -1 | -7 | -11 | -19 | -77 | -133 | -209 | -1,463 | -32,369 | -226,583 | -356,059 | -615,011 | -2,492,413 | -4,305,077 | -6,765,121 | -47,355,847 |
