Find the composite number following.
46,56,98,70,30.

Dear student,
A composite number is a positive integer which has factors other than 1 and itself.

so, $46=2\times 23$
      $56=2\times 2\times 2\times 7$
      $98=2\times 7\times 7$
      $70=2\times 5\times 7$
      $30=2\times 3\times 5$

from observation of factorisation all above numbers we can say that all of above numbers are composite numbers.

Regards,
