As a product of its prime factors: 2*2*17 = 68
As a product of its prime factors: 2*2*19 = 76
As a product of its prime factors: 2*2*23 = 92
2 x 2 x 17 = 682 x 2 x 19 = 762 x 2 x 23 = 922 x 2 = 4, the GCF
Assuming that "prome factorizayion" is your fail at spelling prime factorisation, 68 = 2*2*17 76 = 2*2*19 92 = 2*2*23 Therefore, GCF = 2*2 = 4.
92 = 22 × 23

92 = 2 x 2 x 23
2 x 2 x 23 = 92
92 = 22 x 231

2x2x23
Oh, dude, 92 is like 2 x 2 x 23. So, the prime factorization of 92 is 2^2 x 23. Just a couple of twos hanging out with a 23, no big deal.
The median is 78.
