The primary decomposition of 70 is 2 x 5 x 7. To put it differently, 70 can be expressed as a product of its primary elements 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. Such prime factors are the fundamental components 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 factors. In essence, we are breaking down the number 70 into its component prime factors. Decomposing the number 70 into its primary divisors 2, 5, and 7 is called the prime factorization of 70. By doing this we are expressing 70 as a multiplication of its prime factors.
