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 2,024,545, 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 | 2,024,545 | |
| -1 | -2,024,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,024,545.
Example:
1 x 2,024,545 = 2,024,545
and
-1 x -2,024,545 = 2,024,545
Notice both answers equal 2,024,545
With that explanation out of the way, let's continue. Next, we take the number 2,024,545 and divide it by 2:
2,024,545 ÷ 2 = 1,012,272.5
If the quotient is a whole number, then 2 and 1,012,272.5 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 | 2,024,545 | |
| -1 | -2,024,545 |
Now, we try dividing 2,024,545 by 3:
2,024,545 ÷ 3 = 674,848.3333
If the quotient is a whole number, then 3 and 674,848.3333 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 | 2,024,545 | |
| -1 | -2,024,545 |
Let's try dividing by 4:
2,024,545 ÷ 4 = 506,136.25
If the quotient is a whole number, then 4 and 506,136.25 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 | 2,024,545 | |
| -1 | 2,024,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 101 | 211 | 505 | 1,055 | 1,919 | 4,009 | 9,595 | 20,045 | 21,311 | 106,555 | 404,909 | 2,024,545 |
| -1 | -5 | -19 | -95 | -101 | -211 | -505 | -1,055 | -1,919 | -4,009 | -9,595 | -20,045 | -21,311 | -106,555 | -404,909 | -2,024,545 |
