Question

Find the HCF of 24, 31 and 48 by prime factorisation​

Answer 1

Answer:

Factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24. Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and 36. Therefore, common factor of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. Highest common factor (H.C.F) of 24 and 36 = 12.

19 and 31 are prime numbers. So, HCF (19, 31) = 1

Solution : Factorizing the number, HCF is the highest common factor, The HCF of 48 and 28 is 4.
