lcm = 2×3×5

=30

b) hcf of 90 and 150 =

Find the prime factorization of 90

90 = 2 × 3 × 3 × 5

Find the prime factorization of 150

150 = 2 × 3 × 5 × 5

To find the HCF, multiply all the prime factors common to both numbers:

Therefore, HCF = 2 × 3 × 5

HCF = 30

c) the prime factors of 60 are 2, 3, 5. Therefore, the product of prime factors = 2 × 3 × 5 = 30.

d) Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.
