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 773,360,533, 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 | 773,360,533 | |
| -1 | -773,360,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 773,360,533.
Example:
1 x 773,360,533 = 773,360,533
and
-1 x -773,360,533 = 773,360,533
Notice both answers equal 773,360,533
With that explanation out of the way, let's continue. Next, we take the number 773,360,533 and divide it by 2:
773,360,533 ÷ 2 = 386,680,266.5
If the quotient is a whole number, then 2 and 386,680,266.5 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 | 773,360,533 | |
| -1 | -773,360,533 |
Now, we try dividing 773,360,533 by 3:
773,360,533 ÷ 3 = 257,786,844.3333
If the quotient is a whole number, then 3 and 257,786,844.3333 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 | 773,360,533 | |
| -1 | -773,360,533 |
Let's try dividing by 4:
773,360,533 ÷ 4 = 193,340,133.25
If the quotient is a whole number, then 4 and 193,340,133.25 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 | 773,360,533 | |
| -1 | 773,360,533 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 97 | 253 | 1,067 | 2,231 | 24,541 | 31,513 | 346,643 | 724,799 | 3,056,761 | 7,972,789 | 33,624,371 | 70,305,503 | 773,360,533 |
| -1 | -11 | -23 | -97 | -253 | -1,067 | -2,231 | -24,541 | -31,513 | -346,643 | -724,799 | -3,056,761 | -7,972,789 | -33,624,371 | -70,305,503 | -773,360,533 |
