The HCF of two numbers is (15) and their LCM is (630). Which statement is definitely true?
Answer and explanation
Correct answer: The product of the two numbers is (9450)
Step 1: For two numbers, product (=) HCF (\times) LCM. Step 2: Therefore, the product is (15\times 630=9450). The sum or the exact numbers are not fixed without more information. Step 3: In relation-based questions, choose only what is definitely proved.
