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 47,179,685, 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 | 47,179,685 | |
| -1 | -47,179,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,179,685.
Example:
1 x 47,179,685 = 47,179,685
and
-1 x -47,179,685 = 47,179,685
Notice both answers equal 47,179,685
With that explanation out of the way, let's continue. Next, we take the number 47,179,685 and divide it by 2:
47,179,685 ÷ 2 = 23,589,842.5
If the quotient is a whole number, then 2 and 23,589,842.5 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 | 47,179,685 | |
| -1 | -47,179,685 |
Now, we try dividing 47,179,685 by 3:
47,179,685 ÷ 3 = 15,726,561.6667
If the quotient is a whole number, then 3 and 15,726,561.6667 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 | 47,179,685 | |
| -1 | -47,179,685 |
Let's try dividing by 4:
47,179,685 ÷ 4 = 11,794,921.25
If the quotient is a whole number, then 4 and 11,794,921.25 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 | 47,179,685 | |
| -1 | 47,179,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 367 | 1,835 | 2,569 | 3,673 | 12,845 | 18,365 | 25,711 | 128,555 | 1,347,991 | 6,739,955 | 9,435,937 | 47,179,685 |
| -1 | -5 | -7 | -35 | -367 | -1,835 | -2,569 | -3,673 | -12,845 | -18,365 | -25,711 | -128,555 | -1,347,991 | -6,739,955 | -9,435,937 | -47,179,685 |
