The prime factors are 2, 2, 2, 2, 2, 2, 47 Others are combinations of the primes, i.e. 2 x 2 = 4 2 x 2 x 2 = 8 2 x 2 x 2 x 2 = 16 2 x 2 x 2 x 2 x 2 = 32 2 x 2 x 2 x 2 x 2 x 2 = 64 2 x 47 = 94 2 x 2 x 47 = 188 2 x 2 x 2 x 47 = 376 2 x 2 x 2 x 2 x 47 = 752 2 x 2 x 2 x 2 x 2 x 47 = 1504
213 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 8192
2 x 2 x 2 x 2 x 2 = 322 x 2 x 2 x 2 x 3 = 482 x 2 x 2 x 2 x 2 x 2 = 642 x 2 x 2 x 3 x 3 = 722 x 2 x 2 x 2 x 5 = 802 x 2 x 2 x 2 x 2 x 3 = 96
384 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3
768 is even, so let's start by dividing it by 2. 768 = 2 x 384 = 2 x 2 x 192 = 2 x 2 x 2 x 96 = 2 x 2 x 2 x 2 x 48 = 2 x 2 x 2 x 2 x 2 x 24 = 2 x 2 x 2 x 2 x 2 x 2 x 12 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 6 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 The end number is now prime, so the prime factorisation is complete. 768 = 28 x 3.
