48. This is because 1*2=2, 2+3=5, 5*2=10, 10+3=13, 13*2=26, 26+3=29, but 29*2≠48.

How about: 1+2+3+20 = 26 out of many other combinations
(3 cubed +1 squared) - 2 = 26 also written as (3^3 + 1^2) - 2 = 26 or (27+1)-2 = 26 so 3,3,2,2 and 1 can make 26
3 x 4 = 12... 1 + 12 = 13... 13 x 2= 26
The two numbers are coprime, so their greatest common factor is 1.
Factors of 39: 1, 3, 13, 39 Factors of 26: 1, 2, 13, 26 Common factors: 1, 13.
The prime njumbers from 1 to 26 are 2, 3, 5, 7, 11, 13, 17, 19, and 23.
