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 28,490,075, 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 | 28,490,075 | |
| -1 | -28,490,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,490,075.
Example:
1 x 28,490,075 = 28,490,075
and
-1 x -28,490,075 = 28,490,075
Notice both answers equal 28,490,075
With that explanation out of the way, let's continue. Next, we take the number 28,490,075 and divide it by 2:
28,490,075 ÷ 2 = 14,245,037.5
If the quotient is a whole number, then 2 and 14,245,037.5 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 | 28,490,075 | |
| -1 | -28,490,075 |
Now, we try dividing 28,490,075 by 3:
28,490,075 ÷ 3 = 9,496,691.6667
If the quotient is a whole number, then 3 and 9,496,691.6667 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 | 28,490,075 | |
| -1 | -28,490,075 |
Let's try dividing by 4:
28,490,075 ÷ 4 = 7,122,518.75
If the quotient is a whole number, then 4 and 7,122,518.75 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 | 28,490,075 | |
| -1 | 28,490,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 67 | 73 | 233 | 335 | 365 | 1,165 | 1,675 | 1,825 | 4,891 | 5,825 | 15,611 | 17,009 | 24,455 | 78,055 | 85,045 | 122,275 | 390,275 | 425,225 | 1,139,603 | 5,698,015 | 28,490,075 |
| -1 | -5 | -25 | -67 | -73 | -233 | -335 | -365 | -1,165 | -1,675 | -1,825 | -4,891 | -5,825 | -15,611 | -17,009 | -24,455 | -78,055 | -85,045 | -122,275 | -390,275 | -425,225 | -1,139,603 | -5,698,015 | -28,490,075 |
