The lcm of two prime numbers a and b is _________  a/baba+b1

If two positive integers p and q can be expressed as p = ab2 and q = a3b ;   a, b being prime numbers, then LCM (p, q) isaba2b2a3b2a3b3

If a, b are integers such that a > b then lcm(a, b) lies in _________     a>lcm(a, b)>b     a>b>lcm(a, b)      lcm(a, b)>=a>b     none of the mentioned

If two positive integers p and q can be expressed as p=ab^ 2 \& q = a ^ 3 * b where a, b being prime numbers then LCM (p, q) is equal to a. ab b. a ^ 2 * b ^ 2 c. a ^ 3 * b ^ 2 d. a ^ 2 * b ^ 3

Select the correct answerIf the LCM and HCF of two numbers are equal, then the numbers must be OptionsEqualComposite Numbers Prime NumbersCo- prime Numbers

Assertion (A): The HCF of two numbers is 5 and their product is 150. Then their LCM is 40. Reason(R): For any two positive integers a and b, HCF (a, b) × LCM (a, b) = a × bChoose the correct option.
