The prime factorization of 70 is 2 x 5 x 7. In other words, 70 can be expressed as a product of its primary elements which are 2, 5, and 7. Expressing 70 as a result of its divisors 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 process of prime factorization on 70, we can determine that 2, 5, and 7 are its main elements. Basically, we are splitting down the number 70 into its component prime elements. Breaking down the number 70 into its prime divisors 2, 5, and 7 is called the prime factorization of 70. This process we are representing 70 as a multiplication of its prime factors.
