WebLARGEST PRIME DIVISOR OF AN ODD PERFECT NUMBER 957 n is feasible with respect to q. We shall complete our proof by showing that for each prime in T the assertion that the prime in question is q is incompatible with the requirement of feasibility for each of the pi in (2). (a) q - 3. The only feasible powers of 3 are 32 ,36 ,38 ,326. If 32 1 n ... WebWhen checking to see if a Mersenne number is prime, we usually first look for any small divisors. The following theorem of Euler and Fermat is very useful in this regard. Theorem Three: Let p and q be odd primes. If q divides M p = 2 p-1, then q = +/-1 (mod 8) and q = 2kp + 1. for some integer k . WebThe number 3 has only two factors. That is, it is only divisible by 3 and 1. (Without leaving a remainder). Thus 3 is a prime number. The number 2 is the smallest prime number. Interestingly, its the only even prime number which means all other prime numbers are odd. kara wild attorney
