The primary decomposition for 70 is 2 x 5 x 7. To put it differently, 70 can be expressed as a product of its primary elements which are 2, 5, and 7. Expressing 70 as a product of its divisors 2, 5, and 7 is known as the prime factorization of 70. Such divisors are the building blocks that compose 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 elements. Basically, we are breaking down the number 70 into its component prime factors. Splitting the number 70 into its prime factors 2, 5, and 7 is called the prime factorization of 70. This process we are representing 70 as a product of its prime factors.
