Answer 1

hcf of 12 and 924

924=12*76+6

12 =6*2+0

therefore: hcf= 6

lcm of 12 and 924:

lcm=924

such numbers are called Co- prime nos

Answer 2

Answer:

2

Step-by-step explanation:

HCF = 12

Let numbers are 12a and 12b respectively

LCM ⇒ 12xy = 924(given)

⇒ab = 77

⇒ Possible pairs are

= (1 × 77) (7 × 11)
