The main decomposition regarding 70 is 2 x 5 x 7. Put simply, 70 can be expressed as a product of its prime elements that 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 make up the number 70. By performing the method 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 factors. Splitting the number 70 into its primary divisors 2, 5, and 7 is called the prime factorization of 70. By doing this we are representing 70 as a multiplication of its prime factors.
