The main decomposition of 70 is 2 x 5 x 7. To put it differently, 70 can be expressed as a product of its prime 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. These divisors are the building blocks that form the number 70. By performing the process of finding the prime factors on 70, we can determine that 2, 5, and 7 are its prime factors. Essentially, we are breaking down the number 70 into its constituent prime elements. Breaking down 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.
