WebIf n is not a power of 2, it is either a prime q or a product r cdot m, in which r is an odd prime. In the second case, you find algebraic factors according to the identity (2^m)^r + 1 = (2^m + 1). ( (2^m)^ (r-1) - (2^m)^ (r-2) ….. + 1 ). In the first case, if the prime q = 2, you have q = n = power of two. Web14 nov. 2016 · Step 1: Show it is true for n = 1 n = 1. 1 is the smallest odd number. 1 is the smallest odd number. 41 + 51 + 61 = 15 4 1 + 5 1 + 6 1 = 15, which is divisible by 15 15. Therefore it is true for n = 1 n = 1. Step 2: Assume that it is true for n = k n = k. That is, 4k + 5k + 6k = 15M 4 k + 5 k + 6 k = 15 M.
