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 771,453,629, 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 | 771,453,629 | |
| -1 | -771,453,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 771,453,629.
Example:
1 x 771,453,629 = 771,453,629
and
-1 x -771,453,629 = 771,453,629
Notice both answers equal 771,453,629
With that explanation out of the way, let's continue. Next, we take the number 771,453,629 and divide it by 2:
771,453,629 ÷ 2 = 385,726,814.5
If the quotient is a whole number, then 2 and 385,726,814.5 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 | 771,453,629 | |
| -1 | -771,453,629 |
Now, we try dividing 771,453,629 by 3:
771,453,629 ÷ 3 = 257,151,209.6667
If the quotient is a whole number, then 3 and 257,151,209.6667 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 | 771,453,629 | |
| -1 | -771,453,629 |
Let's try dividing by 4:
771,453,629 ÷ 4 = 192,863,407.25
If the quotient is a whole number, then 4 and 192,863,407.25 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 | 771,453,629 | |
| -1 | 771,453,629 |
If you did it right, you will end up with this table:
| 1 | 47 | 107 | 131 | 1,171 | 5,029 | 6,157 | 14,017 | 55,037 | 125,297 | 153,401 | 658,799 | 5,888,959 | 7,209,847 | 16,413,907 | 771,453,629 |
| -1 | -47 | -107 | -131 | -1,171 | -5,029 | -6,157 | -14,017 | -55,037 | -125,297 | -153,401 | -658,799 | -5,888,959 | -7,209,847 | -16,413,907 | -771,453,629 |
