    \(324=2^{2}\times 3^{4}\\ 224=2^{2}\times 61\\ 514=2^{3}\times 257\\ 136=2^{3}\times 3^{4}\)

    sum of digits \(324\rightarrow 9\\ 224\rightarrow 8\\ 514\rightarrow 10\\ 136\rightarrow 10\)

    Using sum of digits, a) is the odd man out. Also, d) is odd man out considering the one's digit.

    @mathmath333 , there's something wrong with your prime factorizations. And the second number is 244, not 224.

    b) too @ospreytriple because its first digit isn't odd!

    this one \(324=2^{2}\times 3^{4}\\ 244=2^{2}\times 61\\ 514=2\times 257\\ 136=2^{3}\times 3^{4}\)

    @mathmath333 , \(136 = 2^3 \times 17\)

    It could be argued that 514 is the odd one as its prime factorisation contains only two primes. Or even the answer is none of above as all of the options are numbers not man.
