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 764,114,465, 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 | 764,114,465 | |
| -1 | -764,114,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,114,465.
Example:
1 x 764,114,465 = 764,114,465
and
-1 x -764,114,465 = 764,114,465
Notice both answers equal 764,114,465
With that explanation out of the way, let's continue. Next, we take the number 764,114,465 and divide it by 2:
764,114,465 ÷ 2 = 382,057,232.5
If the quotient is a whole number, then 2 and 382,057,232.5 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 | 764,114,465 | |
| -1 | -764,114,465 |
Now, we try dividing 764,114,465 by 3:
764,114,465 ÷ 3 = 254,704,821.6667
If the quotient is a whole number, then 3 and 254,704,821.6667 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 | 764,114,465 | |
| -1 | -764,114,465 |
Let's try dividing by 4:
764,114,465 ÷ 4 = 191,028,616.25
If the quotient is a whole number, then 4 and 191,028,616.25 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 | 764,114,465 | |
| -1 | 764,114,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 149 | 395 | 745 | 11,771 | 12,983 | 58,855 | 64,915 | 1,025,657 | 1,934,467 | 5,128,285 | 9,672,335 | 152,822,893 | 764,114,465 |
| -1 | -5 | -79 | -149 | -395 | -745 | -11,771 | -12,983 | -58,855 | -64,915 | -1,025,657 | -1,934,467 | -5,128,285 | -9,672,335 | -152,822,893 | -764,114,465 |
