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 2,250,895, 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 | 2,250,895 | |
| -1 | -2,250,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,250,895.
Example:
1 x 2,250,895 = 2,250,895
and
-1 x -2,250,895 = 2,250,895
Notice both answers equal 2,250,895
With that explanation out of the way, let's continue. Next, we take the number 2,250,895 and divide it by 2:
2,250,895 ÷ 2 = 1,125,447.5
If the quotient is a whole number, then 2 and 1,125,447.5 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 | 2,250,895 | |
| -1 | -2,250,895 |
Now, we try dividing 2,250,895 by 3:
2,250,895 ÷ 3 = 750,298.3333
If the quotient is a whole number, then 3 and 750,298.3333 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 | 2,250,895 | |
| -1 | -2,250,895 |
Let's try dividing by 4:
2,250,895 ÷ 4 = 562,723.75
If the quotient is a whole number, then 4 and 562,723.75 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 | 2,250,895 | |
| -1 | 2,250,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 529 | 851 | 2,645 | 4,255 | 12,167 | 19,573 | 60,835 | 97,865 | 450,179 | 2,250,895 |
| -1 | -5 | -23 | -37 | -115 | -185 | -529 | -851 | -2,645 | -4,255 | -12,167 | -19,573 | -60,835 | -97,865 | -450,179 | -2,250,895 |
