Is 730 is a Composite number

 Is 730 is a composite number or not ?

  • As we already know that, the number having factors 1 and the number itself is the prime number.
  • And numbers having more than these two factors are the composite numbers.
  • To check whether the number 730 is composite or not first we have to find its factors.

 

Factors of 730:

  • If we have taken numbers from 1, 2, 3…for checking factors of 730, we found that 730 has factors 1, 2, 5, 10, 73, 146, 365 and 730. Hence, we must say that 730 is a composite number.
  • Thus, 730 is the composite umber.
  • If we multiply 730 by 1, 2, 3 then we get the multiples of 730 which are 730, 1460 and so on.

 

About the number 730:

  • 730 has more than two factors which are 1, 2, 5, 10, 73, 146, 365 and 730 and hence it is the composite number.
  • 730 is the even composite number and it is not the perfect square also.
  • If we divide 730 by 1, 2, 5, 10, 73, 146, 365 and 730 then we get remainder as zero. Hence, 1, 2, 5, 10, 73, 146, 365 and 730 are the factors of 730.

 

Note:

  • 730 is not the perfect square.
  • Factors of 730: 1, 2, 5, 10, 73, 146, 365 and 730
  • Prime factors of 730: 2, 5, 73

 

Conclusion:

  • 730 is the composite number which has factors 1, 2, 5, 10, 73, 146, 365 and 730
  • And hence, 730 is not the prime number.
