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 864,526,177, 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 | 864,526,177 | |
| -1 | -864,526,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 864,526,177.
Example:
1 x 864,526,177 = 864,526,177
and
-1 x -864,526,177 = 864,526,177
Notice both answers equal 864,526,177
With that explanation out of the way, let's continue. Next, we take the number 864,526,177 and divide it by 2:
864,526,177 ÷ 2 = 432,263,088.5
If the quotient is a whole number, then 2 and 432,263,088.5 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 | 864,526,177 | |
| -1 | -864,526,177 |
Now, we try dividing 864,526,177 by 3:
864,526,177 ÷ 3 = 288,175,392.3333
If the quotient is a whole number, then 3 and 288,175,392.3333 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 | 864,526,177 | |
| -1 | -864,526,177 |
Let's try dividing by 4:
864,526,177 ÷ 4 = 216,131,544.25
If the quotient is a whole number, then 4 and 216,131,544.25 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 | 864,526,177 | |
| -1 | 864,526,177 |
If you did it right, you will end up with this table:
| 1 | 17 | 97 | 223 | 1,649 | 2,351 | 3,791 | 21,631 | 39,967 | 228,047 | 367,727 | 524,273 | 3,876,799 | 8,912,641 | 50,854,481 | 864,526,177 |
| -1 | -17 | -97 | -223 | -1,649 | -2,351 | -3,791 | -21,631 | -39,967 | -228,047 | -367,727 | -524,273 | -3,876,799 | -8,912,641 | -50,854,481 | -864,526,177 |
