Answer 2

Answer:

If GCD of two numbers is 1 then LCM is equal to the product of those two numbers.

Step-by-step explanation:  

Co-prime numbers:

• The two numbers whose highest common factor is 1 then those numbers are called co-prime numbers.  
• Co-prime numbers are a collection of integers or numbers with only 1 as their highest common factor (HCF) or Greatest common divisor(GCD).
• Relatively prime or mutually prime numbers are other names for co-prime numbers. In order to create co-prime numbers, two numbers are required.

HCF and LCM of Co-Prime numbers:

• Since the HCF of two Co-Prime numbers = 1 and
• LCM of two Co-Prime numbers (m,n) = Product of two numbers (m,n).

      Given G.C.D of two numbers = 1

      Let the two numbers be x and y.

           If GCD of x and y = 1 then LCM = product of x and y.

      So, if GCD(x,y) = 1 then LCM(x,y) = xy
