1. The number
60 and 90 are both divisible by 2,3,5, 10, 15 and 30
what is HCF of 60 and 90​

Answer 1

Answer :

30

Step-by-step explanation :

Prime Factorisation of the given numbers :

→ 60 = 2 × 2 × 3 × 5

→ 90 = 2 × 3 × 3 × 5

Mark the common terms in both the Prime Factorisation, we get

→ HCF(60, 90) = 2 × 3 × 5 = 30

Hence, the HCF of 60 and 90 is 30.
