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 744,103,517, 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 | 744,103,517 | |
| -1 | -744,103,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 744,103,517.
Example:
1 x 744,103,517 = 744,103,517
and
-1 x -744,103,517 = 744,103,517
Notice both answers equal 744,103,517
With that explanation out of the way, let's continue. Next, we take the number 744,103,517 and divide it by 2:
744,103,517 ÷ 2 = 372,051,758.5
If the quotient is a whole number, then 2 and 372,051,758.5 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 | 744,103,517 | |
| -1 | -744,103,517 |
Now, we try dividing 744,103,517 by 3:
744,103,517 ÷ 3 = 248,034,505.6667
If the quotient is a whole number, then 3 and 248,034,505.6667 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 | 744,103,517 | |
| -1 | -744,103,517 |
Let's try dividing by 4:
744,103,517 ÷ 4 = 186,025,879.25
If the quotient is a whole number, then 4 and 186,025,879.25 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 | 744,103,517 | |
| -1 | 744,103,517 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 761 | 971 | 1,007 | 14,459 | 18,449 | 40,333 | 51,463 | 738,931 | 766,327 | 977,797 | 14,039,689 | 39,163,343 | 744,103,517 |
| -1 | -19 | -53 | -761 | -971 | -1,007 | -14,459 | -18,449 | -40,333 | -51,463 | -738,931 | -766,327 | -977,797 | -14,039,689 | -39,163,343 | -744,103,517 |
