(v) If a number say x is a factor of another number say y then the H.C.F. of `x and y` is x and their L.C.M. is y.

75% of a number x is equal to 2/5 of an another number y. What is the ratio between x and y?

H.C.F. xx L.C.M. = Product of two numbers. The sum of two numbers is 135 and their H.C.F. is 27. If their L.C.M. is 162, the numbers are

(vi) The H.C.F.of given numbers is always is a factors of their L.C.M.

If H.C.F. of x and y is z, then H.C.F. of (x)/(z)and(y)/(z) is :
