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

We know that for any two positive integers a and b, HCF (a, b) × LCM (a, b) = a × b.

Here HCF = 13, a = 26 and b = 169

Then,

13 × LCM = 26 × 169

LCM = (26 × 169) / 13

LCM = 338

If the LCM of a and 18 is 36 and the HCF of a and 18 is 2, then a =

The HCF of 95 and 152, is

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