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 752,768,485, 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 | 752,768,485 | |
| -1 | -752,768,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 752,768,485.
Example:
1 x 752,768,485 = 752,768,485
and
-1 x -752,768,485 = 752,768,485
Notice both answers equal 752,768,485
With that explanation out of the way, let's continue. Next, we take the number 752,768,485 and divide it by 2:
752,768,485 ÷ 2 = 376,384,242.5
If the quotient is a whole number, then 2 and 376,384,242.5 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 | 752,768,485 | |
| -1 | -752,768,485 |
Now, we try dividing 752,768,485 by 3:
752,768,485 ÷ 3 = 250,922,828.3333
If the quotient is a whole number, then 3 and 250,922,828.3333 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 | 752,768,485 | |
| -1 | -752,768,485 |
Let's try dividing by 4:
752,768,485 ÷ 4 = 188,192,121.25
If the quotient is a whole number, then 4 and 188,192,121.25 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 | 752,768,485 | |
| -1 | 752,768,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 272,249 | 1,361,245 | 1,905,743 | 9,528,715 | 21,507,671 | 107,538,355 | 150,553,697 | 752,768,485 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -272,249 | -1,361,245 | -1,905,743 | -9,528,715 | -21,507,671 | -107,538,355 | -150,553,697 | -752,768,485 |
