The prime factorization of 70 is 2 x 5 x 7. In other words, 70 can be expressed as a product of its primary factors that are 2, 5, and 7. Expressing 70 as a product of its prime factors 2, 5, and 7 is known as prime decomposition of 70. Such prime factors are the building blocks that form the number 70. By performing the method of prime factorization on 70, we can determine that 2, 5, and 7 are its main elements. Basically, we are breaking down the number 70 into its constituent prime factors. Splitting the number 70 into its primary factors 2, 5, and 7 is called the prime factorization of 70. This process we are representing 70 as a multiplication of its fundamental elements.
