65, 70, 75, 80, 85, 90, 95, and 100 are.
Common multiples of 100 and 2 include any multiple of 100.
28, 56
1 and 2
10 is two in multiples of 2 to 100
LCM(1, 2, 3, ... , 100) = 26*34*52*72*11*13*17*19*23*29*31*37*41*43*47*53*59*61*67*71*73*79*83*89*97 = 7284218307581900599279651679808748132800. All common multiples are multiples of this number.
the multiples of 2 are 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,70,72,74,76,78,80,82,84,86,88,90,92,94,96,98,100
22, 44, 66, and 88.
112, 126, 140 and so on.
Use the methods you probably already learned, to find the least common multiple of 2 and 3. Then multiply this least common multiple by 1, by 2, by 3, etc., to get additional multiples.
They have to be multiples of 15 so all of them will be multiples of 3. They all have to be even so you are left with 30, 60, 90
The multiples of 2 are all the positive even numbers. For them to be common, they need to be compared to another set of multiples.
Multiples of 2 include every even number. For them to be common, they need to be compared to another set of multiples.
