Explain why 3 × 5 × 7 + 7 is a composite number. Solution: A composite number is a number that is divisible by another number other than by itself and one. The number 2 is the only even prime number. All other even numbers are composite numbers. As per BODMAS rule: 3 × 5 × 7 + 7 = 105 + 7 = 112. 112 is an even number. Therefore,112 is a ...
We have, 3 × 5 × 7 + 7 = 7[3 × 5 + 1], Which is not a prime number because it has a factor 7, i.e. it has more than two factors. Hence, it is a composite number.
