Highest Common Factor of A and B is 60 and C = 24. What is the Highest Common Factor of A, B and C?
Show answer & explanation
Correct answer: B
Explanation
Given:
HCF (A, B) = 60
C = 24
According to the formula:
HCF (A, B, C) = HCF [HCF (A, B), C]
HCF (60, 24)
60 = 2² × 3 × 5
24 = 2³ × 3
HCF = 2² × 3 = 12
