Question

L.C.M of 2 or more mutually prime number is given by what?

Answer 1

LCM OF TWO OR MORE PRIME NUMBER IS GIVEN BY THEIR MULTIPLICATION

EX- LCM OF 5,7,9=5x7x9=315

Answer 2

common multiple of two numbers is a composite number that both numbers can divide evenly. That means that if those numbers have no prime factors in common, then indeed, their product is the smallest common multiple of the two.

Compare this to two non-prime numbers: 4 and 6. The prime factors of 4 are 2 and 2, the prime factors of 6 are 2 and 3. So the least common multiple will be the maximum number of factors of 2 (that's two) and the maximum number of factors of 3 (that's one). So it is 2 x 2 x 3 = 12.
