The multiples of 20 are 20, 40, 60, 80, 100, 120... The multiples of 30 are 30, 60, 90, 120, 150... The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135... The common multiples of 20, 30, and 15 are 60, 120, 180, 240...
The LCM of 20 and 30 is 60. The multiples of 20 are 20, 40, 60, and so on. The multiples of 30 are 30, 60, and so on. So teh LCM of 20 and 30 is 60.
5 - 10 - 15 - 20 - 25 - 30
Assuming positive multiples, 5, 10, 15, 20, 25, 30
10+20+30 = 60
The multiples of 20 are 20, 40, 60, 80, 100, 120... The multiples of 30 are 30, 60, 90, 120, 150... The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135... The common multiples of 20, 30, and 15 are 60, 120, 180, 240...
The LCM of 20 and 30 is 60. The multiples of 20 are 20, 40, 60, and so on. The multiples of 30 are 30, 60, and so on. So teh LCM of 20 and 30 is 60.
20, 40, 60 and so on. 30, 60, 90 and so on. Common multiples include 60, 120, 180 and so on.
multiples of 3 ... 21, 24, 27, 30 (between means leave out 30 multiples of 6 ... 24, 30 so the answer is 24
5: 5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100,105,110.10: 10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160,170,180,190.
10, 20, 30 and so on.
They are 21 and 28
10 and 20
They are 24 and 28.
10, 20, 30 and so on.
5 - 10 - 15 - 20 - 25 - 30
The set is: 20, 24, 28.
