(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.

If x and y are any two relative prime numbers, then their H.C.f is

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 :

If x and y are any two co-prime, then their L.C.M. is

Statement (P): the relation between L.C.M and H.C.F is product of the numbers = L.C.M xx H.C.F . Statement (Q): If one of the two given numbers is a multiple of the other , then the greater number will be their L.C.M
