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 96,897,055, 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 | 96,897,055 | |
| -1 | -96,897,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 96,897,055.
Example:
1 x 96,897,055 = 96,897,055
and
-1 x -96,897,055 = 96,897,055
Notice both answers equal 96,897,055
With that explanation out of the way, let's continue. Next, we take the number 96,897,055 and divide it by 2:
96,897,055 ÷ 2 = 48,448,527.5
If the quotient is a whole number, then 2 and 48,448,527.5 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 | 96,897,055 | |
| -1 | -96,897,055 |
Now, we try dividing 96,897,055 by 3:
96,897,055 ÷ 3 = 32,299,018.3333
If the quotient is a whole number, then 3 and 32,299,018.3333 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 | 96,897,055 | |
| -1 | -96,897,055 |
Let's try dividing by 4:
96,897,055 ÷ 4 = 24,224,263.75
If the quotient is a whole number, then 4 and 24,224,263.75 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 | 96,897,055 | |
| -1 | 96,897,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 79 | 95 | 395 | 1,501 | 7,505 | 12,911 | 64,555 | 245,309 | 1,019,969 | 1,226,545 | 5,099,845 | 19,379,411 | 96,897,055 |
| -1 | -5 | -19 | -79 | -95 | -395 | -1,501 | -7,505 | -12,911 | -64,555 | -245,309 | -1,019,969 | -1,226,545 | -5,099,845 | -19,379,411 | -96,897,055 |
