The Maths Prof: Highest Common Factor (HCF) / Greatest Common Factor (GCF) of 140 & 126
In this lesson I show you how to find the Highest Common Factor (also known as Greatest Common Factor) of two numbers, 140 & 126. The exam question is taken from a Cambridge IGCSE paper 0580/21/O/N/23. I have used the prime factorisation method. Watch part 2 • The Maths Prof: Highest Common Factor (HCF... to find HCF of 3 numbers! 😄
