What is the least common multiple of 2 6 and 7?

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 2, 6, and 7 is 42.


What is the least common multiple of 3 7 and 6?

It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!


What is the least common multiple of 14 and 42?

The LCM of 14 and 42 is 42. The simplest method to determine the least common multiple in this case is to notice that 42 is a multiple of 14. Since 42 is a multiple of 14, the least common multiple is 42. To determine the least common multiple of two numbers, you can also determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 14 are 2 and 7. The prime factors of 42 are 2, 3, and 7. The greatest common factor of 14 and 42 is 14. So, the least common multiple of 14 and 42 is (2x7) x (2x3x7) ÷ 14 = 42.


What are the common multiples of 7 14 and 21?

The common multiples of 7, 14, and 21 are the infinite set of multiples of their least common multiple, which is 42. So the common multiplesof 7, 14, and 21 are 42, 84, 126, 168, and so on.Any multiple of 42.


What is the least common multiple of 7 and 21?

The LCM of 7 and 21 is 21. Since 7 is a factor of 21, the LCM is automatically 21.21 is.
