The least common multiple is 6 because 2,3,and 6 all have 6 as one of their multiples.
What are 2 multiples that 3 and 5 have in common
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.
6 : 7
The most common multiples are 13 3 3234 2 2 2 2 232
The first three common multiples of 2 and 3 are... 6, 12 and 18.
60 and its multiples
They are all multiples of 6
78 and any of its multiples
What are three common multiples of 2 6 8
lcm(2, 3, 5) = 30 → 2 digit common multiples are 30, 60, 90.
There are eleven such numbers.Get the common multiple of those numbers. All other common multiples will be multiples of this common multiple; that is, you can multiply the common multiple by 1, by 2, by 3, etc. to get additional numbers that are multiples of both numbers.
Get the first common multiple, then multiply that by 0, 1, 2, 3, 4, etc. to get additional common multiples.
