Is 700 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 700 is composite or not first we have to find its factors.

Factors of 700:
- If we have taken numbers from 1, 2, 3…for checking factors of 700, we found that 700 has factors 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350 and 700. Hence, we must say that 700 is a composite number.
- Thus, 700 is the composite umber.
- If we multiply 700 by 1, 2, 3 then we get the multiples of 700 which are 700, 1400 and so on.
About the number 700:
- 700 has more than two factors which are 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350 and 700 and hence it is the composite number.
- 700 is the even composite number and it is not the perfect square also.
- If we divide 700 by 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350 and 700 then we get remainder as zero. Hence, 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350 and 700 are the factors of 700.
Note:
- 700 is not the perfect square.
- Factors of 700: 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350 and 700
- Prime factors of 700: 2, 5, 7
Conclusion:
- 700 is the composite number which has factors 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350 and 700
- And hence, 700 is not the prime number.
