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 47,427,209, 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 | 47,427,209 | |
| -1 | -47,427,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,427,209.
Example:
1 x 47,427,209 = 47,427,209
and
-1 x -47,427,209 = 47,427,209
Notice both answers equal 47,427,209
With that explanation out of the way, let's continue. Next, we take the number 47,427,209 and divide it by 2:
47,427,209 ÷ 2 = 23,713,604.5
If the quotient is a whole number, then 2 and 23,713,604.5 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 | 47,427,209 | |
| -1 | -47,427,209 |
Now, we try dividing 47,427,209 by 3:
47,427,209 ÷ 3 = 15,809,069.6667
If the quotient is a whole number, then 3 and 15,809,069.6667 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 | 47,427,209 | |
| -1 | -47,427,209 |
Let's try dividing by 4:
47,427,209 ÷ 4 = 11,856,802.25
If the quotient is a whole number, then 4 and 11,856,802.25 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 | 47,427,209 | |
| -1 | 47,427,209 |
If you did it right, you will end up with this table:
| 1 | 29 | 53 | 59 | 523 | 1,537 | 1,711 | 3,127 | 15,167 | 27,719 | 30,857 | 90,683 | 803,851 | 894,853 | 1,635,421 | 47,427,209 |
| -1 | -29 | -53 | -59 | -523 | -1,537 | -1,711 | -3,127 | -15,167 | -27,719 | -30,857 | -90,683 | -803,851 | -894,853 | -1,635,421 | -47,427,209 |
