6, 12, 18, 24, 30 & 36.
Any multiple of 120.
No. The least common multiple is the number of the smallest positive integer that is a multiple of both numbers.Example: 8 and 6. the Multiples of 8 are 8, 16, 24, 32, 40, 48...The multiples of 6 are 6, 12, 18, 24, 30, 36, 40, 46...These numbers have common multiples of both 24 and 40, so the "least" common multiple would be 24. The least common multiple of two numbers will never be less than either number.
The multiples of 8 are 8, 16, 24, 32, 40, 48, and so on. The multiples of 12 are 12, 24, 36, 48, 60, 72, and so on.
Multiples of 4 are 4, 8,12, 16, 20, 24, 28, 32, 36, 40, etc. Multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, etc. All numbers that are multiples of 12 are also multiples of 4 because 4 is a factor of 12. The first ten common multiples of 4 and 12 are: 12, 24, 36, 48, 60, 72, 84, 96, 108, and 120
the multiples of 8 are 8 16 24 32 40 48 ... etc
LCM of 24, 40, and 84 is 840. Just write out the multiples of each until you get to a common number.
