Q43 of 128 Page 25

If p₁ and p₂ are distinct primes, their g. c. d is

p₁ and p₂ are distinct prime numbers.

So, 1 is the only common factor among them.

Therefore, g. c. d of them is 1.

If g. c. d of two numbers is 8 and their product is 384, then their l.c.m.. is

If l.c.m.. of two numbers (greater than 1) is the product of them, then their g. c. d is ……

If p, q, r are distinct primes, their l.c.m.. is ……

g. c. d (15, 24, 40) = …….
