Patterns, Properties, and a Pretty Procedure!If one number is a factor of the other (like 6 is a factor of 18 ), then: The HCF is the smaller number. The LCM is the larger number. Hence, for numbers 6 & 18 HCF if 6 LCM is 18 Now, let’s answer some questions If π‘š is a number (and the HCF), what could the other number be? The other number can be any multiple of π’Ž. Because, for π‘š to be the HCF, it must divide the other number fully. Example: If π‘š=5, the other number could be 10, 15, 20 etc. Question (b): If 7π‘˜ is a number (and the HCF), what could the other number be? The other number can be any multiple of πŸ•π’Œ. Example: 14π‘˜, 21π‘˜, 28π‘˜.
