Answer 1

1. Find the smallest number having five different prime factors

Ans. To calculate this interesting number you need to use the five smallest prime numbers. A Prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors that is 2310. You can take different prime numbers for different numbers.

2.What is the difference between a point 100m above sea level and 45m below sea level?
