The main decomposition of 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 prime factors are the fundamental components 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 factors. Basically, we are breaking down the number 70 into its component prime elements. Splitting the number 70 into its prime divisors 2, 5, and 7 is called finding the prime factors of 70. By doing this we are representing 70 as a multiplication of its fundamental elements.
