## Re: a maths questionPrime number is the natural number, which is greater than 1 and divisible by one and by itself only, is called a prime number.
For eg- 3, 3 is divisible 3 & 1 Composite number which is greater than 1 and is not prime and is called a composite number i.e it is divisble by number other than itself and 1. For Eg- 8- divisible by 2,4,8,1. In this case 7*11*13+13= 1014 1014 is divisible by 2,3,6,13,39,26 Since 1014 is divisible by more than the number itself and 1, it is a composite number. 7*6*5*4*3*2*1+5= 5045 5045 is divisible by 5 & 1009 Since 5045 is divisible by more than the number itself and 2, it is a composite number. - pspoornima
