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 722,472,673, 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 | 722,472,673 | |
| -1 | -722,472,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 722,472,673.
Example:
1 x 722,472,673 = 722,472,673
and
-1 x -722,472,673 = 722,472,673
Notice both answers equal 722,472,673
With that explanation out of the way, let's continue. Next, we take the number 722,472,673 and divide it by 2:
722,472,673 ÷ 2 = 361,236,336.5
If the quotient is a whole number, then 2 and 361,236,336.5 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 | 722,472,673 | |
| -1 | -722,472,673 |
Now, we try dividing 722,472,673 by 3:
722,472,673 ÷ 3 = 240,824,224.3333
If the quotient is a whole number, then 3 and 240,824,224.3333 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 | 722,472,673 | |
| -1 | -722,472,673 |
Let's try dividing by 4:
722,472,673 ÷ 4 = 180,618,168.25
If the quotient is a whole number, then 4 and 180,618,168.25 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 | 722,472,673 | |
| -1 | 722,472,673 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 227 | 611 | 2,951 | 5,209 | 10,669 | 67,717 | 138,697 | 244,823 | 1,182,443 | 3,182,699 | 15,371,759 | 55,574,821 | 722,472,673 |
| -1 | -13 | -47 | -227 | -611 | -2,951 | -5,209 | -10,669 | -67,717 | -138,697 | -244,823 | -1,182,443 | -3,182,699 | -15,371,759 | -55,574,821 | -722,472,673 |
