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 4,090,225, 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 | 4,090,225 | |
| -1 | -4,090,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,090,225.
Example:
1 x 4,090,225 = 4,090,225
and
-1 x -4,090,225 = 4,090,225
Notice both answers equal 4,090,225
With that explanation out of the way, let's continue. Next, we take the number 4,090,225 and divide it by 2:
4,090,225 ÷ 2 = 2,045,112.5
If the quotient is a whole number, then 2 and 2,045,112.5 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 | 4,090,225 | |
| -1 | -4,090,225 |
Now, we try dividing 4,090,225 by 3:
4,090,225 ÷ 3 = 1,363,408.3333
If the quotient is a whole number, then 3 and 1,363,408.3333 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 | 4,090,225 | |
| -1 | -4,090,225 |
Let's try dividing by 4:
4,090,225 ÷ 4 = 1,022,556.25
If the quotient is a whole number, then 4 and 1,022,556.25 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 | 4,090,225 | |
| -1 | 4,090,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 79 | 95 | 109 | 395 | 475 | 545 | 1,501 | 1,975 | 2,071 | 2,725 | 7,505 | 8,611 | 10,355 | 37,525 | 43,055 | 51,775 | 163,609 | 215,275 | 818,045 | 4,090,225 |
| -1 | -5 | -19 | -25 | -79 | -95 | -109 | -395 | -475 | -545 | -1,501 | -1,975 | -2,071 | -2,725 | -7,505 | -8,611 | -10,355 | -37,525 | -43,055 | -51,775 | -163,609 | -215,275 | -818,045 | -4,090,225 |
