- 3950 has more than two factors which are 1, 2, 5, 10, 25, 79, 158, 395, 790, 1975 and 3950 and hence it is the composite number.
- 3950 is the even composite number and it is not the perfect square also.
- If we divide 3950 by, 1, 2, 5, 10, 25, 79, 158, 395, 790, 1975 and 3950 then we get remainder as zero. Hence, 1, 2, 5, 10, 25, 79, 158, 395, 790, 1975 and 3950 are the factors of 3950.
Note:
- 3950 is not the perfect square.
- Factors of 3950: 1, 2, 5, 10, 25, 79, 158, 395, 790, 1975 and 3950
- Prime factors of 3950: 2, 5, 79
Conclusion:
- 3950 is the composite number which has factors, 1, 2, 5, 10, 25, 79, 158, 395, 790, 1975 and 3950
- And hence, 3950 is not the prime number.
