The difference of the squares of two consecutive natural numbers is 2008 (1) Only one such pair exists(2) Infinitely many such pairs exist(3) No such pair exists(4) Exactly two such pairs exist

The HCF of two consecutive natural numbers is 0 (b) 1 (c) 2 (d) non-existant

The HCF of two consecutive natural numbers is (a)0 (b) 1 (c) 2 (d) non-existant

About the number of pairs which have 16 as their H.C.F. and 136 as their L.C.M., we can definitely say that (a) no such pair exists (b) only one such pair exists (c) only two such pairs exist (d) many such pairs exist

The product of two natural numbers is 15120 and their HCF is 6.Find how many such pairs exist.

Magnetic poles always exist in pairs.
