How can a natural number have a limited number of products ?Rafe wrote:$a,b,c,d,.....$ is a sequence.the number of products of $a,b,c,d,....$ is $2,3,4,5,....$ find the minimum value of a in natural number
Factor means prime factor or only factor?Rafe wrote:a,b,c,d,.....is a sequence.the number of factors of a,b,c,d,....is 2,3,4,5,....find the minimum value of a in natural number
I think that is it. And, so, $a=2$Fahim Shahriar wrote:I think you're talking about this sequence
$2,4,8,16.....,2^n$
$2^n$ has $(n+1)$ factors.
...... that really was a lousy mistake.Prosenjit Basak wrote:I don't think so.You said $a=4$.But $4$ has $3$ factors. But in the question Rafe said $a$ has $2$ factors. So $a$ can't be $4$. I think Fahim Bhai may be correct.
