Multiply 35 by the first three counting numbers. That will give you the first three multiples. To be common, they need to be compared to another set of multiples. If you meant 3 and 5, the LCM is 15. Multiplying 15 by 2 and 3 will give you the others.
Theyt are ; - 30, 45, 60. 3 x 6 = 30 3 x 15 = 45 3 x 20 = 60 15 x 2 = 30 ] 15 x 3 = 45 15 x 4 = 60
