hree number are in the ratio of 3 : 4 : 5 and their l . c . m . is 2400 . their h . c . f . is :
let the numbers be 3 x , 4 x and 5 x . then , their l . c . m . = 60 x . so , 60 x = 2400 or x = 40 . the numbers are ( 3 x 40 ) , ( 4 x 40 ) and ( 5 x 40 ) . hence , required h . c . f . = 40 . answer : a
divide(2400, multiply(multiply(3, 4), 5))
