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 7,482,485, 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 | 7,482,485 | |
| -1 | -7,482,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,482,485.
Example:
1 x 7,482,485 = 7,482,485
and
-1 x -7,482,485 = 7,482,485
Notice both answers equal 7,482,485
With that explanation out of the way, let's continue. Next, we take the number 7,482,485 and divide it by 2:
7,482,485 ÷ 2 = 3,741,242.5
If the quotient is a whole number, then 2 and 3,741,242.5 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 | 7,482,485 | |
| -1 | -7,482,485 |
Now, we try dividing 7,482,485 by 3:
7,482,485 ÷ 3 = 2,494,161.6667
If the quotient is a whole number, then 3 and 2,494,161.6667 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 | 7,482,485 | |
| -1 | -7,482,485 |
Let's try dividing by 4:
7,482,485 ÷ 4 = 1,870,621.25
If the quotient is a whole number, then 4 and 1,870,621.25 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 | 7,482,485 | |
| -1 | 7,482,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 79 | 95 | 395 | 997 | 1,501 | 4,985 | 7,505 | 18,943 | 78,763 | 94,715 | 393,815 | 1,496,497 | 7,482,485 |
| -1 | -5 | -19 | -79 | -95 | -395 | -997 | -1,501 | -4,985 | -7,505 | -18,943 | -78,763 | -94,715 | -393,815 | -1,496,497 | -7,482,485 |
