Prove that 151 is prime Prove that 151 is prime Prove that 1

Solution

Answer:

A number P is said to be prime if it has only two factors 1 and P.

consider the number 151 .

To show that the number 151 is prime it is enough to prove it has only two factors(divisors) 1 and 151.

Foa a contradiction if there exists another number s ( s is neither 1 nor 151 ) such that s is a factor of 151.

then their product must be equal to 151 that is 1x151xs=151 which implies that s=1 which is a contradiction to our assumption that s is not 1. Hence the number 151 has only two factors ( divisors ) 1 and itself that proves 151 is a prime number
