• A. 12
• B. 360
• C. 4
• D. 6

Answer 1

Answer:

A. 12

Let’s find the HCF (Highest Common Factor) of 24, 36, and 60.

Prime factorization:

• (24 = 2^3 \times 3)

• (36 = 2^2 \times 3^2)

• (60 = 2^2 \times 3 \times 5)

  Common prime factors (with smallest powers):

• (2^2)

• (3^1)

  HCF:

$2^2 \times 3 = 4 \times 3 = \boxed{12}$

✅ HCF = 12
