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 2,228,975, 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 | 2,228,975 | |
| -1 | -2,228,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,228,975.
Example:
1 x 2,228,975 = 2,228,975
and
-1 x -2,228,975 = 2,228,975
Notice both answers equal 2,228,975
With that explanation out of the way, let's continue. Next, we take the number 2,228,975 and divide it by 2:
2,228,975 ÷ 2 = 1,114,487.5
If the quotient is a whole number, then 2 and 1,114,487.5 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 | 2,228,975 | |
| -1 | -2,228,975 |
Now, we try dividing 2,228,975 by 3:
2,228,975 ÷ 3 = 742,991.6667
If the quotient is a whole number, then 3 and 742,991.6667 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 | 2,228,975 | |
| -1 | -2,228,975 |
Let's try dividing by 4:
2,228,975 ÷ 4 = 557,243.75
If the quotient is a whole number, then 4 and 557,243.75 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 | 2,228,975 | |
| -1 | 2,228,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 47 | 175 | 235 | 271 | 329 | 1,175 | 1,355 | 1,645 | 1,897 | 6,775 | 8,225 | 9,485 | 12,737 | 47,425 | 63,685 | 89,159 | 318,425 | 445,795 | 2,228,975 |
| -1 | -5 | -7 | -25 | -35 | -47 | -175 | -235 | -271 | -329 | -1,175 | -1,355 | -1,645 | -1,897 | -6,775 | -8,225 | -9,485 | -12,737 | -47,425 | -63,685 | -89,159 | -318,425 | -445,795 | -2,228,975 |
