The prime factorization for 70 is 2 x 5 x 7. To put it differently, 70 can be expressed as a product of its prime factors which are 2, 5, and 7. Expressing 70 as a product of its divisors 2, 5, and 7 is known as prime decomposition of 70. These divisors are the building blocks that make up the number 70. By performing the process of prime factorization on 70, we can determine that 2, 5, and 7 are its main elements. Essentially, we are splitting down the number 70 into its component prime factors. Splitting the number 70 into its primary divisors 2, 5, and 7 is called the prime factorization of 70. This process we are expressing 70 as a product of its prime factors.
