What is prime quantity logic?
Logic − We will divide 42 by each quantity better than 1 and smaller than 42. So, 42/2 = 21 i.e. 42 is divisible by 2, this implies 42 just isn’t a major quantity as a result of it’s divisible by one other quantity. 7 just isn’t divisible by 6, This implies that 7 is divisible by only one and seven this implies 7 is a major quantity.
