On Highest Common Factor and Least Common Multiple in the Secondary School Mathematics Curriculum.
Peer reviewed Peer reviewed
Davies, H. B. – International Journal of Mathematical Education in Science and Technology, 1980
Attention is drawn to an ancient Greek method for finding the least common multiple (LCM) of two numbers. A link is established between this method and a well-known method of obtaining the highest common factor (HCF) numbers. This leads to consideration of some relationships between HCF and LCM.
