What is the HCF of any two consecutive even numbers?
The Highest Common Factor (H.C.F) of two consecutive numbers is 2. However, this might also vary depending on the characters. This is because if there are different larger even numbers, the H.C.F will also be a large number. Check out for examples on http://www.tcyonline.com/onlineCAT/HCF%20&%20LCM.pdf.
