Question

If x and y are co primes then their LCM is

Answer 1

if X and y r co prime then their LCM is 1

Answer 2

Answer:

LCM ( x,y ) = xy

Step-by-step explanation:

Since x and y are co primes, they have only 1 as a common factor. All other factors are different.

Hence, if, by prime factorisation,

x = a1 × a2 × ... × an

y = b1 × b2 × ... × bn,

a1, a2, ... , an, b1, b2, ... , bn are all distinct.

Hence, LCM ( x,y ) = ( a1 × a2 × ... × an ) × ( b1 × b2 × ... × bn ) = x × y = xy
