There are infinitely many numbers that are multiples of both 5 and 6. They are multiples of their lowest common multiple, which for 5 and 6 is 30; ie they are the numbers:
30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510, 540, 570, 600, 630, 660, 690, 720, 750, 780, 810, 840, 870, 900, 930, 960, 990, 1020, 1050, 1080, 1110, 1140, 1170, 1200, 1230, 1260, 1290, 1320, 1350, 1380, 1410, 1440, 1470, 1500, 1530, 1560, 1590, 1620, 1650, 1680, 1710, 1740, 1770, 1800, 1830, 1860, 1890, 1920, 1950, 1980, 2010, 2040, 2070, 2100, 2130, 2160, 2190, 2220, 2250, 2280, 2310, 2340, 2370, 2400, 2430, 2460, 2490, 2520, 2550, 2580, 2610, 2640, 2670, 2700, 2730, 2760, 2790, 2820, 2850, 2880, 2910, 2940, 2970, 3000, ...
Pick any two you like.
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
30 is the Least Common Multiple of 2, 5 and 6. All multiples of 30 are divisible by 2, 5 and 6
There is an infinite number of common multiples for 5 6 and 9. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 5 6 and 9 is 90.
There is an infinite number of common multiples for 5 6 and 7. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 5 6 and 7 is 210.
30, 60, 90, 120, 150

30, 60, 90, 120, 150
The first five multiples of 6 are 6, 12, 18, 24 and 30. For them to be common, they need to be compared to another set of multiples.
6 and 12
This cannot be answered because the common multiples of any two or more numbers are infinite.
Alright, sweetheart, buckle up. The multiples for 5 are 5, 10, 15, 20, 25, 30, and so on. For 6, we've got 6, 12, 18, 24, 30, 36, and the list goes on. Now go forth and conquer those multiples, champ.
