Answer 2

Answer:

The HCF of three numbers i.e HCF(12, 45, 75)=3  

Step-by-step explanation:

Given 3 numbers 12, 45 and 75  

we have to find the HCF of above 3 numbers

we will find the HCF by prime factorization method

The factors are

12=2×2×3.

45=5×3×3.

75=5×5×3.    

The highest common factor from the above these factors is 3

Hence, HCF(12, 45, 75)=3
