The video tutorial explores the role of factorials in Pascal's Triangle, focusing on the unique patterns formed by prime numbers. It explains why rows corresponding to prime numbers have all their binomial coefficients divisible by the row number, while non-prime rows do not. The tutorial uses examples to illustrate these concepts and hints at further exploration of the underlying mathematical principles.
