Dear Student,You have written that; X×Y=240 amd LCM=4199     (Where X is prime number and Y is composite number)Which cannot be true, Because multiple of two number cannot be smaller than their LCM
So,ASSUMPTION: Instead of X×Y=240, there should be X+Y=240
Now,LCM=4199=13×17×19All three prime factor of LCM are prime number
So, there are 3 set of (X, Y)If, X=13, Then Y=17×19=323⇒(X, Y)=(13, 323)If, X=17, Then Y=13×19=247⇒(X, Y)=(17, 247)If, X=19, Then Y=13×17=221⇒(X, Y)=(19, 221)Regards

if x is prime,y is a composite number such that xmultipley=240 and their lcm is 4199.find x and y.
