Question

Find the hcf of 35,42 by prime factorisation method

Answer 1

Answer:

7

Step-by-step explanation:

42 = 2 x 3 x 7

35 = 5 x 7

since 7 is the only common factor in both

so 7 is the H.C.F.

Answer 2

Answer:

7

Step-by-step explanation: To find the GCF of 35 and 42, we will find the prime factorization of the given numbers, i.e. 35 = 5 × 7; 42 = 2 × 3 × 7. ⇒ Since 7 is the only common prime factor of 35 and 42. Hence, GCF (35, 42) = 7.
