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 47,263,105, 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 | 47,263,105 | |
| -1 | -47,263,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,263,105.
Example:
1 x 47,263,105 = 47,263,105
and
-1 x -47,263,105 = 47,263,105
Notice both answers equal 47,263,105
With that explanation out of the way, let's continue. Next, we take the number 47,263,105 and divide it by 2:
47,263,105 ÷ 2 = 23,631,552.5
If the quotient is a whole number, then 2 and 23,631,552.5 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 | 47,263,105 | |
| -1 | -47,263,105 |
Now, we try dividing 47,263,105 by 3:
47,263,105 ÷ 3 = 15,754,368.3333
If the quotient is a whole number, then 3 and 15,754,368.3333 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 | 47,263,105 | |
| -1 | -47,263,105 |
Let's try dividing by 4:
47,263,105 ÷ 4 = 11,815,776.25
If the quotient is a whole number, then 4 and 11,815,776.25 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 | 47,263,105 | |
| -1 | 47,263,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 83 | 305 | 415 | 1,867 | 5,063 | 9,335 | 25,315 | 113,887 | 154,961 | 569,435 | 774,805 | 9,452,621 | 47,263,105 |
| -1 | -5 | -61 | -83 | -305 | -415 | -1,867 | -5,063 | -9,335 | -25,315 | -113,887 | -154,961 | -569,435 | -774,805 | -9,452,621 | -47,263,105 |
