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 7,348,145, 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 | 7,348,145 | |
| -1 | -7,348,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,348,145.
Example:
1 x 7,348,145 = 7,348,145
and
-1 x -7,348,145 = 7,348,145
Notice both answers equal 7,348,145
With that explanation out of the way, let's continue. Next, we take the number 7,348,145 and divide it by 2:
7,348,145 ÷ 2 = 3,674,072.5
If the quotient is a whole number, then 2 and 3,674,072.5 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 | 7,348,145 | |
| -1 | -7,348,145 |
Now, we try dividing 7,348,145 by 3:
7,348,145 ÷ 3 = 2,449,381.6667
If the quotient is a whole number, then 3 and 2,449,381.6667 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 | 7,348,145 | |
| -1 | -7,348,145 |
Let's try dividing by 4:
7,348,145 ÷ 4 = 1,837,036.25
If the quotient is a whole number, then 4 and 1,837,036.25 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 | 7,348,145 | |
| -1 | 7,348,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 2,957 | 14,785 | 20,699 | 103,495 | 209,947 | 1,049,735 | 1,469,629 | 7,348,145 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -2,957 | -14,785 | -20,699 | -103,495 | -209,947 | -1,049,735 | -1,469,629 | -7,348,145 |
