    Identify the number whose prime factorisation has three\[2's\], four \[3's\] and\[a\text{ }5\].

    A)  \[3240\]                       

    B)                     \[2430\]                       

    C)                     \[3420\]                       

    D)                     \[2304\]

    Correct Answer: A

    Solution :

    The product of factors in the prime factorization of a number \[=(2\times 2\times 2)\]\[\times (3\times 3\times 3\times 3)\times 5\] \[\therefore \]The number \[=\] The product of the given prime factors\[=3240\]
