Answer 1

Answer:

C)

Step-by-step explanation:

a. - s. 19 is the HCF of 19 and 76.

76 = 19 × 2 x 2

19 = 19 × 1

Since 19 is the only common factor, 19 is the HCF of 19 and 76.

b. - q. LCM of 10 and 1000 =

10 = 5 × 2 (10)

1000 = 5 × 2 × 5 × 2 × 5 × 2 (10 × 10 × 10)

LCM of these 2 numbers = 10³ = 1000

c. - p. HCF of 73 and 97 -

73 = 73 × 1

97 = 97 × 1

Since there is no common factor except 1, the HCF is 1.

d. - r. LCM of these 2 numbers -

Since there is no common factor between 73 and 97, we must multiply them to get the LCM.

73 x 97 = 7081

Therefore, the correct option is C).
