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 4,947,371, 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 | 4,947,371 | |
| -1 | -4,947,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,947,371.
Example:
1 x 4,947,371 = 4,947,371
and
-1 x -4,947,371 = 4,947,371
Notice both answers equal 4,947,371
With that explanation out of the way, let's continue. Next, we take the number 4,947,371 and divide it by 2:
4,947,371 ÷ 2 = 2,473,685.5
If the quotient is a whole number, then 2 and 2,473,685.5 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 | 4,947,371 | |
| -1 | -4,947,371 |
Now, we try dividing 4,947,371 by 3:
4,947,371 ÷ 3 = 1,649,123.6667
If the quotient is a whole number, then 3 and 1,649,123.6667 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 | 4,947,371 | |
| -1 | -4,947,371 |
Let's try dividing by 4:
4,947,371 ÷ 4 = 1,236,842.75
If the quotient is a whole number, then 4 and 1,236,842.75 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 | 4,947,371 | |
| -1 | 4,947,371 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 29 | 143 | 319 | 377 | 1,193 | 4,147 | 13,123 | 15,509 | 34,597 | 170,599 | 380,567 | 449,761 | 4,947,371 |
| -1 | -11 | -13 | -29 | -143 | -319 | -377 | -1,193 | -4,147 | -13,123 | -15,509 | -34,597 | -170,599 | -380,567 | -449,761 | -4,947,371 |
