(1) 24 (11) 12 (III) 36 (IV) 48​

Answer 1

Answer:

HCF = 12

Step-by-step explanation:

TO FIND : HCF of 60,72,24

solution

first of all find prime factors of each number,

60 = (2) × (2) × (3) × 5

72 = (2) × (2) × 2 × (3) × 3

24 = (2) × (2) × 2 × (3)

now select the factors which are common for all three { I have marked common factor by bracket }

HCF = (2) × (2) × (3)

HCF = 12
