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 4,947,481, 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 | 4,947,481 | |
| -1 | -4,947,481 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,947,481.
Example:
1 x 4,947,481 = 4,947,481
and
-1 x -4,947,481 = 4,947,481
Notice both answers equal 4,947,481
With that explanation out of the way, let's continue. Next, we take the number 4,947,481 and divide it by 2:
4,947,481 ÷ 2 = 2,473,740.5
If the quotient is a whole number, then 2 and 2,473,740.5 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 | 4,947,481 | |
| -1 | -4,947,481 |
Now, we try dividing 4,947,481 by 3:
4,947,481 ÷ 3 = 1,649,160.3333
If the quotient is a whole number, then 3 and 1,649,160.3333 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 | 4,947,481 | |
| -1 | -4,947,481 |
Let's try dividing by 4:
4,947,481 ÷ 4 = 1,236,870.25
If the quotient is a whole number, then 4 and 1,236,870.25 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 | 4,947,481 | |
| -1 | 4,947,481 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 67 | 77 | 137 | 469 | 539 | 737 | 959 | 1,507 | 3,283 | 5,159 | 6,713 | 9,179 | 10,549 | 36,113 | 64,253 | 73,843 | 100,969 | 449,771 | 706,783 | 4,947,481 |
| -1 | -7 | -11 | -49 | -67 | -77 | -137 | -469 | -539 | -737 | -959 | -1,507 | -3,283 | -5,159 | -6,713 | -9,179 | -10,549 | -36,113 | -64,253 | -73,843 | -100,969 | -449,771 | -706,783 | -4,947,481 |
