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 747,440,683, 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 | 747,440,683 | |
| -1 | -747,440,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 747,440,683.
Example:
1 x 747,440,683 = 747,440,683
and
-1 x -747,440,683 = 747,440,683
Notice both answers equal 747,440,683
With that explanation out of the way, let's continue. Next, we take the number 747,440,683 and divide it by 2:
747,440,683 ÷ 2 = 373,720,341.5
If the quotient is a whole number, then 2 and 373,720,341.5 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 | 747,440,683 | |
| -1 | -747,440,683 |
Now, we try dividing 747,440,683 by 3:
747,440,683 ÷ 3 = 249,146,894.3333
If the quotient is a whole number, then 3 and 249,146,894.3333 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 | 747,440,683 | |
| -1 | -747,440,683 |
Let's try dividing by 4:
747,440,683 ÷ 4 = 186,860,170.75
If the quotient is a whole number, then 4 and 186,860,170.75 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 | 747,440,683 | |
| -1 | 747,440,683 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 187 | 253 | 391 | 4,301 | 173,783 | 1,911,613 | 2,954,311 | 3,997,009 | 32,497,421 | 43,967,099 | 67,949,153 | 747,440,683 |
| -1 | -11 | -17 | -23 | -187 | -253 | -391 | -4,301 | -173,783 | -1,911,613 | -2,954,311 | -3,997,009 | -32,497,421 | -43,967,099 | -67,949,153 | -747,440,683 |
