The LCM of 7 21 35 is 105

210. 30 = 2 x 3 x 5 21 = 3 x 7 lcm = 2 x 3 x 5 x 7 = 210

2/3 + 5/7 (the common denominator is 21, the LCM of 3 and 7) = 2*7/3*7 + 5*3/7*3 = 14/21 + 15/21 = (14 + 15)/21 = 29/21 = (21 + 8)/21 = 21/21 + 8/21 = 1 + 8/21 = 1 8/21

Note that 21 x 2 = 42, so we really only need to look at 35 and 42. So 7 x 5 = 35, and 7 x 6 = 42. There is a common factor of 7. So we have 7 x 5 x 6 = 210 is the LCM.
