Answer 1

Answer:

65=3*13

117=3*3*13

273=3*7*13

HCF=13

Answer 2

Step-by-step explanation:

For finding the HCF of 65, 117 and 273 by prime factorisation method, first we'll have to prime factorize the numbers:-

• 65 → 13 × 5

• 117 → 3 × 3 × 13

• 273 → 3 × 7 × 13

Here, we can see that 13 is common in all the three numbers and we knew that HCF (Highest Common Factor) is the highest common factor of the given numbers.

So, 13 is the HCF of 65, 117 and 273
