Answer 1:
59, 61 and 67 are all the primes between 55 and 70
Answer 2:
The Greatest Common Factor of 8 and 3 is 1. It can never be higher than 80. Even if it's the LCM you want, the answer is 24. Maybe you typed the 8 by mistake.
Answer 3:
While searching for common multiples of two different primes, multiply the two and search for the product's multiple.
7*5 = 35
We need a multiple of 35 between 150?
OOps! What do you mean between 150?
