The factor pairs for 72 are these:
(1, 72)
(2, 36)
(3, 24)
(4, 18)
(6, 12)
(8, 9)
1 and 71, 2 and 70, 3 and 69, 4 and 68 -etc, etc.
Negative 2 and negative 36 multiplied together equal 72 -2 x -36 = 72 Remember when you multiply two negative numbers together you get a postivie number. Since 72 is an even number it has to be divisible by 2 so if you divide it by 2 the number you get (36) times 2 equals 72.
17*2*114*12*72
How about: 8*9 = 72
72 = 36 + 36
72 = 1*72 = 2*36 = 3*24 = 4*18 = 6*12 = 8*9
24 & 3
72, 72, and 72.

The Fundamental Theorem of Arithmetic states that every number has exactly one, unique factorization of potentially non-unique prime numbers. Since the prime factorization of 72 is 2*2*2*3*3, we conclude that 72 is coprime with all other prime numbers, so there is no solution.
