Can two number have 18 as their HCF and 380 as their LCM? Give reason

Can two numbers have 18 as their HCF and 146 as their LCM? Give reasons.

If the sum of LCM and HCF of two numbers is 1260 and their LCM is 900 more than their HCF, then the product of two numbers is (a) 203400 (b) 194400 (c) 198400 (d) 205400

Write true (T) or false (F) for each of the following statements: The H.C.F. of two distinct prime numbers is 1. The H.C.F. of two co-prime number is 1 The H.C.F. of an even and an odd numbers is 1. The H.C.F. of two consecutive even number is 2. The H.C.F. of two consecutive odd number is 2

The product of two numbers is 1530 and their HCF is 15. the LCM of these numbers is (a)102 (b)120 (c)84 (d)112

The H.C.F. of 144 and 198 is

the H.C.F. of two numbers is 145, their L.C.M. is 2175. If one number is 725, find the other.
