Factors of 740:
- If we have taken numbers from 1, 2, 3…for checking factors of 740, we found that 740 has factors 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370 and 740. Hence, we must say that 740 is a composite number.
- Thus, 740 is the composite umber.
- If we multiply 740 by 1, 2, 3 then we get the multiples of 740 which are 740, 1480 and so on.
About the number 740:
- 740 has more than two factors which are 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370 and 740 and hence it is the composite number.
- 740 is the even composite number and it is not the perfect square also.
- If we divide 740 by 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370 and 740 then we get remainder as zero. Hence, 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370 and 740 are the factors of 740.
Note:
- 740 is not the perfect square.
- Factors of 740:1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370 and 740
- Prime factors of 740: 2, 5, 37
Conclusion:
- 740 is the composite number which has factors 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370 and 740
- And hence, 740 is not the prime number.
