There is an infinite number of common multiples for these numbers!
There is an infinite number of common multiples for 2 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 2 and 7 is 14.
The 3 numbers don't have a common multiple except for 1.
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.
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.
All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. The smallest of these is known as the least common multiple, or LCM. The LCM of 6 and 7 is 42. Multiples are an infinite set. There is no multiple so large that you can't multiply it with something to get an even larger multiple. Therefore, the greatest common multiple of 6 and 7 (or anything else) is infinite.
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM Other common multiples can be found by multiplying the LCM by successive counting numbers.
There is an infinite number of common multiples for 7 and 14. 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).
504 is the least common multiple of 7, 8 and 9. All numbers that are multiples of 504 are multiples of 7, 8 and 9 as well
The common multiples of 2 and 7 are 14, 28, 42, 56, 70, 84, 98, and so on.
The least common multiple of the numbers 7 and 11 is 77.
77, 154, 231 and so on.
