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 2,338,175, 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 | 2,338,175 | |
| -1 | -2,338,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,338,175.
Example:
1 x 2,338,175 = 2,338,175
and
-1 x -2,338,175 = 2,338,175
Notice both answers equal 2,338,175
With that explanation out of the way, let's continue. Next, we take the number 2,338,175 and divide it by 2:
2,338,175 ÷ 2 = 1,169,087.5
If the quotient is a whole number, then 2 and 1,169,087.5 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 | 2,338,175 | |
| -1 | -2,338,175 |
Now, we try dividing 2,338,175 by 3:
2,338,175 ÷ 3 = 779,391.6667
If the quotient is a whole number, then 3 and 779,391.6667 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 | 2,338,175 | |
| -1 | -2,338,175 |
Let's try dividing by 4:
2,338,175 ÷ 4 = 584,543.75
If the quotient is a whole number, then 4 and 584,543.75 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 | 2,338,175 | |
| -1 | 2,338,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 431 | 775 | 1,085 | 2,155 | 3,017 | 5,425 | 10,775 | 13,361 | 15,085 | 66,805 | 75,425 | 93,527 | 334,025 | 467,635 | 2,338,175 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -431 | -775 | -1,085 | -2,155 | -3,017 | -5,425 | -10,775 | -13,361 | -15,085 | -66,805 | -75,425 | -93,527 | -334,025 | -467,635 | -2,338,175 |
