Question

what is the hcf of 98 and 192

Answer 1

Answer:

   Find the prime factorization of 98

   98 = 2 × 7 × 7

   Find the prime factorization of 192

   192 = 2 × 2 × 2 × 2 × 2 × 2 × 3

   To find the hcf, multiply all the prime factors common to both numbers:

   Therefore, HCF = 2.

Answer 2

Answer:

2

Step-by-step explanation:

By prime factorisation, we get

98 = 2 * 7 * 7

192 = 2 * 2 * 2 * 2 * 2 * 2 * 3

As 2 is common in both the numbers, so 2 is the HCF.
