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 elements which are 2, 5, and 7. 70 can be written as a result of its prime factors 2, 5, and 7 is known as prime decomposition of 70. Such divisors are the building blocks that form the number 70. By performing the method of prime factorization on 70, we can determine that 2, 5, and 7 are its prime elements. In essence, we are breaking down the number 70 into its component prime elements. Decomposing the number 70 into its prime factors 2, 5, and 7 is called the prime factorization of 70. Performing this we are expressing 70 as a multiplication of its fundamental elements.
