Question 4

Divisibility Rules
HCF and LCM are widely used in number system especially in real numbers in finding relationship between different numbers and their general forms. Also, product of two positive integers is equal to the product of their $${HCF}$$ and $${LCM}$$.
Product of numbers $$={HCF} 	imes {LCM}$$
Based on thè above information answer the following questions.
