Question

can two numbers have as 16 as their HCF and 204 as their LCM

Answer 1

HCF of two numbers should be the LCM of those two numbers.

16 is not the factor of 204

So two numbers cannot have 16 as HCF and 204 as LCM.

Answer 2

we know that HCF of a number is the divisor of the LCM og that number.. here 16 is not the divisor of 204..so any two numbers cannot have 16 and 204 as their hcf and lcm respectively
