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 4,272,947, 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 | 4,272,947 | |
| -1 | -4,272,947 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,272,947.
Example:
1 x 4,272,947 = 4,272,947
and
-1 x -4,272,947 = 4,272,947
Notice both answers equal 4,272,947
With that explanation out of the way, let's continue. Next, we take the number 4,272,947 and divide it by 2:
4,272,947 ÷ 2 = 2,136,473.5
If the quotient is a whole number, then 2 and 2,136,473.5 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 | 4,272,947 | |
| -1 | -4,272,947 |
Now, we try dividing 4,272,947 by 3:
4,272,947 ÷ 3 = 1,424,315.6667
If the quotient is a whole number, then 3 and 1,424,315.6667 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 | 4,272,947 | |
| -1 | -4,272,947 |
Let's try dividing by 4:
4,272,947 ÷ 4 = 1,068,236.75
If the quotient is a whole number, then 4 and 1,068,236.75 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 | 4,272,947 | |
| -1 | 4,272,947 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 31 | 49 | 97 | 203 | 217 | 679 | 899 | 1,421 | 1,519 | 2,813 | 3,007 | 4,753 | 6,293 | 19,691 | 21,049 | 44,051 | 87,203 | 137,837 | 147,343 | 610,421 | 4,272,947 |
| -1 | -7 | -29 | -31 | -49 | -97 | -203 | -217 | -679 | -899 | -1,421 | -1,519 | -2,813 | -3,007 | -4,753 | -6,293 | -19,691 | -21,049 | -44,051 | -87,203 | -137,837 | -147,343 | -610,421 | -4,272,947 |
