Can two numbers have 15 as their H.C.F. and 175 as L.C.M. Give reason
No, Two numbers cannot have HCF as 15 and LCM as 175 .
Because (i) LCM>HCF and (ii) HCF of the two numbers should divide the LCM completely.
Here , the 1st criteria is fulfilled but the 2nd criteria is not.
Since, 17515=353 (does not divide completely) ∉ N.
175 is not completely divisible by 15.
