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 7,482,319, 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 | 7,482,319 | |
| -1 | -7,482,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,482,319.
Example:
1 x 7,482,319 = 7,482,319
and
-1 x -7,482,319 = 7,482,319
Notice both answers equal 7,482,319
With that explanation out of the way, let's continue. Next, we take the number 7,482,319 and divide it by 2:
7,482,319 ÷ 2 = 3,741,159.5
If the quotient is a whole number, then 2 and 3,741,159.5 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 | 7,482,319 | |
| -1 | -7,482,319 |
Now, we try dividing 7,482,319 by 3:
7,482,319 ÷ 3 = 2,494,106.3333
If the quotient is a whole number, then 3 and 2,494,106.3333 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 | 7,482,319 | |
| -1 | -7,482,319 |
Let's try dividing by 4:
7,482,319 ÷ 4 = 1,870,579.75
If the quotient is a whole number, then 4 and 1,870,579.75 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 | 7,482,319 | |
| -1 | 7,482,319 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 89 | 223 | 377 | 1,157 | 2,581 | 2,899 | 6,467 | 19,847 | 33,553 | 84,071 | 258,011 | 575,563 | 7,482,319 |
| -1 | -13 | -29 | -89 | -223 | -377 | -1,157 | -2,581 | -2,899 | -6,467 | -19,847 | -33,553 | -84,071 | -258,011 | -575,563 | -7,482,319 |
