Class : Class 8
Master Answer Admin from Revisewise Noida please resolve this doubt and provide explanation. Answer should be C because 0 and 1 can never be multiple of any number. 0 multiplied by any number is 0 only, thus it can never be a multiple. 1 multiplied by any number is the number itself, but any number multiplied by another number is not 1, thus even 1 is not the answer. By choosing Opt. D we deny the fact that there is no such SPECIFIC number (which means we say there is a specific number). So ONLY Option C is correct.Correct, we must report this as error because our doubt has not yet been clarified. SOF PLEASE PLEASE help

Abhinav Huralikoppi from Sanskaar English Medium School , Hubballi
Class : Class 5
The answer should be A or B since if the answer A, that is 0, it can be the answer as any number multiplied by 0 is equal to 0. But, if the answer is B, that is 1, it can be the answer if the question has been framed wrongly, that is, if the question would have been "What is the common factor of all the numbers" since all numbers are divisible by 1. But how could the question possibly go so horribly wrong?
