The LCM of (5, 6, 7) is 210.
35 and 70 both have 7 and 5 as prime factors
The LCM of two consecutive numbers is their product. The LCM of two consecutive multiples of 5 is their product divided by 5. Two consecutive numbers cannot be multiples of 5.
There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
The first common multiple of 3 4 5 and 7 is 420.
Common multiples of 7 and 5 include 35, 70, 140, etc.
Any multiple of 420.
35, 70, 105
The common multiples of 3 and 7 are 21, 42, 63 and so on.
There is an infinite number of common multiples for these numbers!
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
The common multiples of 3, 5, 7, 9, and 11 are the numbers that are divisible by all of these numbers. The least common multiple (LCM) of these numbers is 10395. Therefore, any multiple of 10395 is a common multiple of 3, 5, 7, 9, and 11.
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
