Are prime factors and prime factorization the same?

No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.

What is the HCF of 20 and 12?

To work this out, you need to write both numbers as their prime factors: 20 = 2x2x5 12 = 2x2x3 The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get 4. Therefore 4 is the HCF of 20 and 12.


What is the HCF of 14 and 20?
