Given, LCM+HCF = 7380
Let, HCF be x
LCM will be x+7340
therefore, x + (x + 7340) = 7380
                 2x = 7380-7340
                  2x = 40
                   x = 40/2
                    x= 20
hence, HCF = 20
           LCM = (x+7340) = 20+7340 = 7360
at last, 20 X 7360 = 147200

We know that,
L.C.M. x H.C.F. = product of those two no.s
let L.C.M. x and H.C.F be y
x+y=7380-----------------------(1)
x=y+7340-----------------------(2)
BY SUBSTITUTION
(y+7340)+y=7380
2y=40
y=20
x=y+7340
x=7360
product of mubers= product of their H.C.F and L.C.M
=20x7360
= 147200
