H.C.F and L.C.M of 9 and 11 is....


(a) 99

(b) 108

(c) 119​

Answer 1

Answer:

(a) 99

Step-by-step explanation:

HCF (9, 11)= 1

LCM (9, 11)= 99

Product= 1× 99 = 99

Given :-

• Two numbers 9 and 11.

To Find :-

• Product of HCF(9, 11) & LCM(9, 11).

$\boxed{ \large{ \mathfrak{Solution :- }}}$

Prime factorization of 9 = 3 × 3

Prime factorization of 11 = 11

So, HCF of 9 and 11 = 1

and LCM of 9 and 11 = 3 × 3 × 11 = 99

So, HCF(9, 11) × LCM(9, 11) = 1 × 99 = 99
