You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. I could tell you that the answer is 491356 but how can you be sure that I did not make a mistake? Or that I am not messing about?

with a pencil easier than with a computer and an internet connection.

376320 = 2 X 188160 = 2 X 2 X 94080 = 2 X 2 X 2 X 47040 = 2 X 2 X 2 X 2 X 23520 = 2 X 2 X 2 X 2 X 2 X 11760 = 2 X 2 X 2 X 2 X 2 X 2 X 5880 = 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2940 = 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 1470 = 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 735 = 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 5 X 147 = 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 5 X 3 X 49 = 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 2 X 5 X 3 X 7 X 7. So the prime factorization of 376320 is 29 X 3 X 5 X 72.

You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.The answer is 2^17 = 131072.
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.
4704= 2 x 2352= 2 x 2 x 1176= 2 x 2 x 2 x 588= 2 x 2 x 2 x 2 x 294= 2 x 2 x 2 x 2 x 2 x 147= 2 x 2 x 2 x 2 x 2 x 3 x 49= 2 x 2 x 2 x 2 x 2 x 3 x 7 x 7672= 2 x 336= 2 x 2 x 168= 2 x 2 x 2 x 84= 2 x 2 x 2 x 2 x 42= 2 x 2 x 2 x 2 x 2 x 21= 2 x 2 x 2 x 2 x 2 x 3 x 7The prime factors they have in common are 2 x 2 x 2 x 2 x 2 x 3 x 7, so the greatest common factor is 672.
