Answer 2

Step-by-step explanation:

1. The HCF of 20 and 35 is 5. To calculate the HCF (Highest Common Factor) of 20 and 35, we need to factor each number (factors of 20 = 1, 2, 4, 5, 10, 20; factors of 35 = 1, 5, 7, 35) and choose the highest factor that exactly divides both 20 and 35, i.e., 5.
2. HCF of 18 and 27 by Prime Factorization As visible, 18 and 27 have common prime factors. Hence, the HCF of 18 and 27 is 3 × 3 = 9.
