The ratio of LCM and HCF of the least composite and the least prime numbers is
(a) 1:2
(b) 2:1
(c) 1:1
(d) 1:3

The least prime number is 0 (b) 1 (c) 2 (d) 3

The least prime is 1 (b) 2 (c) 3 (d) 5

The product of LCM and HCF of 3.02 and 1.8 is

The LCM and HCF of two rational numbers are equal,then the numbers must be (a) prime (b) co-prime (c) composite (d) equal

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

The smallest number which is neither prime no composite is 0 (b) 1 (c) 2 (d) 3

What is the HCF of two prime numbers x and y ? A)1 B)2 C) (x)/(y) D)0

The least among the following is (a) 0.2 (b) 1-:0.2( c) 0.2( d ) (0.2)^(2)

Which of the following is the least? sin 3 (b) sin 2 (c) sin 1 (d) sin 7

If the LCM of a and 18 is 36 and the HCF of a and 18 is 2, then a= (a) 2 (b) 3 (c) 4 (d) 1
