A) Prime number
B) Composite number
C) Can't say
D) None of these
Correct Answer: B
Solution :
We have, \[\left( 3\times 5\times 7 \right)+7=105+7=112\] \[\therefore \] Prime factors of \[112=2\times 2\times 2\times 2\times 7\] \[={{2}^{4}}\times 7\] So, it is the product of prime factors 2 and 7. i.e. it has factors other than 1 and itself. Hence, it is a composite number.You need to login to perform this action.
