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 7,320,673, 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 | 7,320,673 | |
| -1 | -7,320,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,320,673.
Example:
1 x 7,320,673 = 7,320,673
and
-1 x -7,320,673 = 7,320,673
Notice both answers equal 7,320,673
With that explanation out of the way, let's continue. Next, we take the number 7,320,673 and divide it by 2:
7,320,673 ÷ 2 = 3,660,336.5
If the quotient is a whole number, then 2 and 3,660,336.5 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 | 7,320,673 | |
| -1 | -7,320,673 |
Now, we try dividing 7,320,673 by 3:
7,320,673 ÷ 3 = 2,440,224.3333
If the quotient is a whole number, then 3 and 2,440,224.3333 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 | 7,320,673 | |
| -1 | -7,320,673 |
Let's try dividing by 4:
7,320,673 ÷ 4 = 1,830,168.25
If the quotient is a whole number, then 4 and 1,830,168.25 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 | 7,320,673 | |
| -1 | 7,320,673 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 47 | 131 | 1,189 | 1,363 | 1,927 | 3,799 | 5,371 | 6,157 | 55,883 | 155,759 | 178,553 | 252,437 | 7,320,673 |
| -1 | -29 | -41 | -47 | -131 | -1,189 | -1,363 | -1,927 | -3,799 | -5,371 | -6,157 | -55,883 | -155,759 | -178,553 | -252,437 | -7,320,673 |
