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 743,447,509, 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 | 743,447,509 | |
| -1 | -743,447,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 743,447,509.
Example:
1 x 743,447,509 = 743,447,509
and
-1 x -743,447,509 = 743,447,509
Notice both answers equal 743,447,509
With that explanation out of the way, let's continue. Next, we take the number 743,447,509 and divide it by 2:
743,447,509 ÷ 2 = 371,723,754.5
If the quotient is a whole number, then 2 and 371,723,754.5 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 | 743,447,509 | |
| -1 | -743,447,509 |
Now, we try dividing 743,447,509 by 3:
743,447,509 ÷ 3 = 247,815,836.3333
If the quotient is a whole number, then 3 and 247,815,836.3333 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 | 743,447,509 | |
| -1 | -743,447,509 |
Let's try dividing by 4:
743,447,509 ÷ 4 = 185,861,877.25
If the quotient is a whole number, then 4 and 185,861,877.25 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 | 743,447,509 | |
| -1 | 743,447,509 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 283 | 1,981 | 8,207 | 12,941 | 57,449 | 90,587 | 375,289 | 2,627,023 | 3,662,303 | 25,636,121 | 106,206,787 | 743,447,509 |
| -1 | -7 | -29 | -203 | -283 | -1,981 | -8,207 | -12,941 | -57,449 | -90,587 | -375,289 | -2,627,023 | -3,662,303 | -25,636,121 | -106,206,787 | -743,447,509 |
