That's an infinite list.
Multiples of what???For example, to get multiples of 20, just start with 20 and add 20 at a time: 20, 40, 60, ...
20 pinkgal333:20, 40, 60 are all common multiples.
20 40
The first four multiples of 20 are: 20 40 60 80
The answer is 40 because 20x2=40 and 5x8=40.
All the multiples of 20 cannot be listed since they are infinite in number. They start 20, 40, 60, 80, 100, ...
Shan't!
the multiples of 20 are 20,40,60,80,100,120,140,160,180,200,220,240,260,280,300,320,340,360,380,400,420,440,460,480,500 and so on. Just keep adding 20!20, 40, 60 and so on.The multiples start with 20. And then 20 is added to every preceding number.For example, 1x20=20.The next multiple would by 20+20= 40. Similarly, the next would 40+20 (Adding 20 to the preceding number- the preceding number would be the second multiple in this case).Thus the multiples will be 20,40,60,80,100,120 and so on. You can't determine all the multiples as the greatest number is unknown.
Not all multiples of 40 are multiples of 80. Only the even multiples of 40 are also multiples of 80. The odd multiples, e.g. 40, 120, 200, 280, and 360, are not multiples of 80.
The LCM of 8, 10, and 20 is 40. Multiples of 8: 8, 16, 24, 32, 40, 48...... Multiples of 10: 10, 20, 30, 40, 50, 60...... Multiples of 20: 20, 40, 60, 80 The smallest number that all three numbers go into evenly is 40. Therefore the LCM of 8, 10, and 20 is 40.
The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, and so on. The multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, and so on.
20, 40 60, 80 and keep adding 20 until you get to 1400.
