If a = 23 × 3, b = 2 × 3 × 5, c = 3n × 5 and LCM (a, b, c) = 23 × 32 × 5, then n =

Q13 of 124 Page 1

If a = 2³ × 3, b = 2 × 3 × 5, c = 3ⁿ × 5 and LCM (a, b, c) = 2³ × 3² × 5, then n =

We know that LCM = Product of the greatest power of each prime factor, involved in the numbers.

Since the power of 3 in LCM is 2,

C = 3²× 5

The HCF of 95 and 152, is

If HCF (26, 169) = 13, then LCM (26, 169) =

The decimal expansion of the rational number 14587 / 1250 will terminate after

If p and q are co-prime numbers, then p² and q² are
