Question

The HCF of 10, 20, 35 is ___.


  1. 5

  2. 10

  3. 4

  4. 2


Solution

The correct option is A

5


The highest common factor of 2 or more than 2 numbers is calculated with the help of prime factorization of each number and taking the multiplication of numbers which are common between those.

10 = 2 x 5
20 = 2 x 2 x 5
35 = 7 x 5

It is clear that only 5 is common in all 3 numbers.
So the HCF of 10, 20, and 35 = 5
