The primary factors 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. 70 can be written 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 prime elements. Essentially, we are breaking down the number 70 into its component prime elements. Decomposing the number 70 into its primary factors 2, 5, and 7 is called the prime factorization of 70. Performing this we are representing 70 as a multiplication of its fundamental elements.
