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 2,024,225, 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 | 2,024,225 | |
| -1 | -2,024,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,024,225.
Example:
1 x 2,024,225 = 2,024,225
and
-1 x -2,024,225 = 2,024,225
Notice both answers equal 2,024,225
With that explanation out of the way, let's continue. Next, we take the number 2,024,225 and divide it by 2:
2,024,225 ÷ 2 = 1,012,112.5
If the quotient is a whole number, then 2 and 1,012,112.5 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 | 2,024,225 | |
| -1 | -2,024,225 |
Now, we try dividing 2,024,225 by 3:
2,024,225 ÷ 3 = 674,741.6667
If the quotient is a whole number, then 3 and 674,741.6667 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 | 2,024,225 | |
| -1 | -2,024,225 |
Let's try dividing by 4:
2,024,225 ÷ 4 = 506,056.25
If the quotient is a whole number, then 4 and 506,056.25 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 | 2,024,225 | |
| -1 | 2,024,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 43 | 175 | 215 | 269 | 301 | 1,075 | 1,345 | 1,505 | 1,883 | 6,725 | 7,525 | 9,415 | 11,567 | 47,075 | 57,835 | 80,969 | 289,175 | 404,845 | 2,024,225 |
| -1 | -5 | -7 | -25 | -35 | -43 | -175 | -215 | -269 | -301 | -1,075 | -1,345 | -1,505 | -1,883 | -6,725 | -7,525 | -9,415 | -11,567 | -47,075 | -57,835 | -80,969 | -289,175 | -404,845 | -2,024,225 |
