(iv) The L.C.M. of two or more co-prime numbers is equal to their product.

L.C.M. of two co-prime numbers is always

The LCM of two coprime numbers is equal to the product of the numbers.

HCF of two co-prime numbers is:

The LCM of two co-prime numbers is their .

Property 2 If a number is divisible by each of two or more co-prime numbers then it is divisible by their products.

(iii) The H.C.F.of two co-prime numbers is 1.

Assertion: Let 13 and 17 are two prime numbers. LCM of 13 and 17 is 221. Reason:The LCM of two prime numbers is always their product.

(vii) The product of the H.C.F.and the L.C.M. of two numbers is equal to the products of the given numbers.That is if a and b are two numbers then a xx b=H.C.F.xx L.C.M.

When will the LCM of two or more numbers be their own product?

The HCF of two co-prime numbers is: (a)2 (b)0 (c)the product of the co-primes (d)1
