Three numbers are in the ratio of 3: 4: 5 and their L.C.M. is 2400. Their H.C.F. is:
30
40
50
60
Let the HCF be `x', so the numbers become 3x, 4x and 5x. LCM of 3x, 4x, 5x can be written as 60x. 60x = 2400 ⟹x = 40.
Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. What is their H.C.F?
The ratio of two numbers is 3 : 4 and their H.C.F. is 4. Their L.C.M. is _____.
