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