Q. 155.0( 1 Vote )

If the product of H.C.F and L.C.M of two natural numbers is 378000, then which of the following can be their H.C.F:

a) 66

b) 130

c) 34

d) 20

Answer :

It is known that the H.C.F is a factor of L.C.M


So,


H.C.F must be a factor of 378000


After checking the options, 20 is the only number which can divide the product 37800 completely without leaving any remainder.


Hence 20 is the Solution.
