that's as far up as it goes because 72 is a composite number not a Prime number!

"The" co-prime number is wrong; for any number, there are infinitely other numbers that are co-prime with it, not just one. Get the prime factors for 72. Then, any number made up of factors that DON'T include those prime factors is co-prime with 72. For example, 49 (which is 7 x 7), or 35 (5 x 7) are coprime with 72, since neither 5 nor 7 are among the prime factors of 72.
there are many (infinite) ways but just one is 72=2*(31+5)
there are 12 prime numbers between 21 and 72 23, 29, 31, 37, 41, 43, 47, 49, 53, 59, 61, 67
98 is an even number, thus it is divisible by 2; 98/2 = 49. 49 is simply 72. Since both 2 and 7 are prime numbers, the prime factorization of 98 is 2 X 72.

No, 72 and 252 are not relatively prime. No pair of even numbers can be relatively prime.
Factor trees create prime numbers. Prime numbers are positive. Since the prime factors of negative 72 are the same as positive 72, you might as well do positive 72. 72 36,2 18,2,2 9,2,2,2 3,3,2,2,2
