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 103,528,055, 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 | 103,528,055 | |
| -1 | -103,528,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,528,055.
Example:
1 x 103,528,055 = 103,528,055
and
-1 x -103,528,055 = 103,528,055
Notice both answers equal 103,528,055
With that explanation out of the way, let's continue. Next, we take the number 103,528,055 and divide it by 2:
103,528,055 ÷ 2 = 51,764,027.5
If the quotient is a whole number, then 2 and 51,764,027.5 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 | 103,528,055 | |
| -1 | -103,528,055 |
Now, we try dividing 103,528,055 by 3:
103,528,055 ÷ 3 = 34,509,351.6667
If the quotient is a whole number, then 3 and 34,509,351.6667 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 | 103,528,055 | |
| -1 | -103,528,055 |
Let's try dividing by 4:
103,528,055 ÷ 4 = 25,882,013.75
If the quotient is a whole number, then 4 and 25,882,013.75 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 | 103,528,055 | |
| -1 | 103,528,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 509 | 2,141 | 2,545 | 9,671 | 10,705 | 40,679 | 48,355 | 203,395 | 1,089,769 | 5,448,845 | 20,705,611 | 103,528,055 |
| -1 | -5 | -19 | -95 | -509 | -2,141 | -2,545 | -9,671 | -10,705 | -40,679 | -48,355 | -203,395 | -1,089,769 | -5,448,845 | -20,705,611 | -103,528,055 |
