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 716,263,033, 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 | 716,263,033 | |
| -1 | -716,263,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 716,263,033.
Example:
1 x 716,263,033 = 716,263,033
and
-1 x -716,263,033 = 716,263,033
Notice both answers equal 716,263,033
With that explanation out of the way, let's continue. Next, we take the number 716,263,033 and divide it by 2:
716,263,033 ÷ 2 = 358,131,516.5
If the quotient is a whole number, then 2 and 358,131,516.5 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 | 716,263,033 | |
| -1 | -716,263,033 |
Now, we try dividing 716,263,033 by 3:
716,263,033 ÷ 3 = 238,754,344.3333
If the quotient is a whole number, then 3 and 238,754,344.3333 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 | 716,263,033 | |
| -1 | -716,263,033 |
Let's try dividing by 4:
716,263,033 ÷ 4 = 179,065,758.25
If the quotient is a whole number, then 4 and 179,065,758.25 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 | 716,263,033 | |
| -1 | 716,263,033 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 397 | 1,081 | 1,669 | 9,131 | 18,659 | 38,387 | 78,443 | 429,157 | 662,593 | 1,804,189 | 15,239,639 | 31,141,871 | 716,263,033 |
| -1 | -23 | -47 | -397 | -1,081 | -1,669 | -9,131 | -18,659 | -38,387 | -78,443 | -429,157 | -662,593 | -1,804,189 | -15,239,639 | -31,141,871 | -716,263,033 |
