Fundamental Theorem of Arithmetic We have discussed about Euclid Division Algorithm in the previous post. Fundamental Theorem of Arithmetic: Statement: Every composite number can be decomposed as a product prime numbers in a unique way, except for the order in which the prime numbers occur. For example: (i) 30 = 2 × 3 × 5, 30 = 3 × 2 × 5, 30 = 2 × 5 × 3 and so on. (ii) … [Read more...] about What Is Fundamental Theorem of Arithmetic
