Question

what is the HCF of 45,30 and 64​

Answer 1

Answer:

Step-by-step explanation:

We know,

45 = 3 × 3 × 5

Prime factors of 45 = 3, 3, 5

30 = 2 × 3 × 5

Prime factors of 30 = 2, 3, 5

64 = 2 × 2 × 2 × 2 × 2

Prime factors of 64 = 2, 2, 2, 2, 2

∵ There is no common factors between 45, 30 and 64.

∴ HCF of 45, 60 and 64 = 1
