If g. c. d (a, b) = 8, l.c.m.. (a, b) = 64 and a > b then a = ……..

We know that g. c. d. (a, b) × l.c.m.. (a, b) = ab

8 × 64 = ab

ab = 512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

Given, g. c. d (a, b) = 8 = 2 × 2 × 2

So, greatest divisor is 8.

Therefore, one of the number is 8.

Therefore the other number is
