28, 56, 84 you can always find a common multiple of two numbers by multiplying them (but that won't always be the least common multiple)... the other common multiples can b found by multiplying that number with any other positive integer... for example, if you have two numbers (a and b), then one of their common multiples is a x b (but not always the smallest one), and the others are 2 x a x b, or any other positive integer times a x b
The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42...The multiples of 6 are 6, 12, 18, 24, 30, 36, 42…The multiples of 7 are 7, 14, 21, 28, 35, 42…The LCM of 3, 6, and 7 is 42.
The LCM is 56.
Any multiple of 21.
154 (there is only one least common multiple)
The first five common multiples of seven and twenty are: 140, 280, 420, 560, 700.
The LCM of consecutive integers is their product. Consecutive integers will not both be multiples of seven.
