Question

The L.C.M. of two numbers is 35 times their H.C.F. . The sum of the H.C.F. and the L.C.M. is 216. If one of the numbers is 30 , then find the other number.

Answer 1

Answer:

42

Step-by-step explanation:

LCM=35x

let HCF IS x

35x+x=216

36x=216

x=216/36=36/6=6

LCM = 35 ×6=210

HCF=6

LCM ×HCF =product of two numbers

let other number is a

one number is 30

30×a=210×6

a=210×6/30=42
