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 47,262,671, 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 | 47,262,671 | |
| -1 | -47,262,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,262,671.
Example:
1 x 47,262,671 = 47,262,671
and
-1 x -47,262,671 = 47,262,671
Notice both answers equal 47,262,671
With that explanation out of the way, let's continue. Next, we take the number 47,262,671 and divide it by 2:
47,262,671 ÷ 2 = 23,631,335.5
If the quotient is a whole number, then 2 and 23,631,335.5 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 | 47,262,671 | |
| -1 | -47,262,671 |
Now, we try dividing 47,262,671 by 3:
47,262,671 ÷ 3 = 15,754,223.6667
If the quotient is a whole number, then 3 and 15,754,223.6667 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 | 47,262,671 | |
| -1 | -47,262,671 |
Let's try dividing by 4:
47,262,671 ÷ 4 = 11,815,667.75
If the quotient is a whole number, then 4 and 11,815,667.75 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 | 47,262,671 | |
| -1 | 47,262,671 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 137 | 271 | 1,273 | 2,603 | 5,149 | 9,179 | 18,157 | 37,127 | 174,401 | 344,983 | 705,413 | 2,487,509 | 47,262,671 |
| -1 | -19 | -67 | -137 | -271 | -1,273 | -2,603 | -5,149 | -9,179 | -18,157 | -37,127 | -174,401 | -344,983 | -705,413 | -2,487,509 | -47,262,671 |
