The first five multiples of 4 are 4, 8, 12, 16 and 20. For them to be common, they need to be compared to another set of multiples.
Any multiples of 20.
The multiples of 20 are20,40,60,80,100,120,140,160,180,200,220...The multiples of 40 are40,80,120,160,200,240,280,420...The three smallest are 40,80,120
The multiples of 246 and 12 are 492 and all the multiples of 492.
12
12 20 28 36 are all multiples of one, two and four.
The only multiple of 12 in that range is 12.
12.
Multiples of 4: 4, 8, 12, 16, 20 Multiples of 10: 10, 20 Therefore, the answer is 20. (:
60 is the lcm
Any multiple of 120.
The first five common multiples of 12 and 20 are: 12 x 5 = 60 20 x 3 = 60 12 x 10 = 120 20 x 6 = 120 12 x 15 = 180 20 x 9 = 180 12 x 20 = 240 20 x 12 = 240 12 x 25 = 300 20 x 15 = 300
