back to boardCan somebody help me, please ? Posted by Abbos 6 Aug 2016 20:38 "Nikolay thinks an integer is interesting if it is a prime number. However, Asya thinks an integer is interesting if the amount of its positive divisors is a prime number " If it so, "Nikolay and Asya are happy when their tastes about some integer are common." How come it can be true, prime number is a number which does not have divisors except for 1 and itself, but it says ,in Asya sentence, that "amount of its positive divisors is a prime number ",Does it mean 1 and the number given ? Can somebody explain it to me and the sample given below the problem , please Re: Can somebody help me, please ? It means that all numbers, which are interesting to Nikolay, are also interesting to Asya, but there are some numbers, which are interested to Asya only. For example, in first sample: 3,5,6,7 are interested to both, 4 is interested only to Asya. And yes, surely divisors of some number include 1 and this number.
