Thirty-five is the LCM of 3/5 + 6/7.
4725.189 = 3*63 = 3*3*21 = 3*3*3*7.75 = 3*25 = 3*5*5.The LCM needs 3 3's, 2 5's and a 7. ... (Leave out the 3 from 75 since there are already 3's in 189.)LCM = 3*3*3*5*5*7 = 27*25*7 = 675*7 = 4725.
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
3=3*1 7=7*1 21=3*7 LCM=(3*7)=(21*1)=21
