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 2,234,155, 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 | 2,234,155 | |
| -1 | -2,234,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,234,155.
Example:
1 x 2,234,155 = 2,234,155
and
-1 x -2,234,155 = 2,234,155
Notice both answers equal 2,234,155
With that explanation out of the way, let's continue. Next, we take the number 2,234,155 and divide it by 2:
2,234,155 ÷ 2 = 1,117,077.5
If the quotient is a whole number, then 2 and 1,117,077.5 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 | 2,234,155 | |
| -1 | -2,234,155 |
Now, we try dividing 2,234,155 by 3:
2,234,155 ÷ 3 = 744,718.3333
If the quotient is a whole number, then 3 and 744,718.3333 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 | 2,234,155 | |
| -1 | -2,234,155 |
Let's try dividing by 4:
2,234,155 ÷ 4 = 558,538.75
If the quotient is a whole number, then 4 and 558,538.75 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 | 2,234,155 | |
| -1 | 2,234,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 829 | 2,695 | 4,145 | 5,803 | 9,119 | 29,015 | 40,621 | 45,595 | 63,833 | 203,105 | 319,165 | 446,831 | 2,234,155 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -829 | -2,695 | -4,145 | -5,803 | -9,119 | -29,015 | -40,621 | -45,595 | -63,833 | -203,105 | -319,165 | -446,831 | -2,234,155 |
