The prime decomposition of 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. 70 can be written as a result of its divisors 2, 5, and 7 is known as prime decomposition of 70. These prime factors are the building blocks that form the number 70. By performing the process of finding the prime factors on 70, we can determine that 2, 5, and 7 are its main factors. In essence, we are splitting down the number 70 into its component prime elements. Splitting the number 70 into its primary divisors 2, 5, and 7 is called finding the prime factors of 70. By doing this we are expressing 70 as a multiplication of its prime factors.
