### Solution:

Concept:
Let's first examine what a factor is.
In mathematics, an integer m that can be multiplied by another integer to create n is known as a divisor of an integer n, also known as a factor of n.A number n is divisible by another number m if and only if m is a divisor of n; this indicates that there is no remainder when dividing n by m.
Now let's calculate the factors of 78.
We shall prime factorise so we get
Therefore,
Now, these prime factors are multiplied singly and then collectively to create the components of $78.$
When we do it, we obtain:
The numbers make up the number $78.$
The required total is 1 + 2 + 3 + 6 + 13 + 26 + 39 + 78, which equals $168.$
Hence, the correct option is 1.
