No because 9 is a composite number having more than 2 factors

72 is composite because it can be divided evenly by numbers other than 1 and itself, such as 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36. 73 is prime because it is only divisible by 1 and itself, with no other factors.

2, 3, 5 are prime numbers but 9 is not a prime number

If the two numbers are relatively prime, their least common multiple is their product. The prime factors of 99 are 3, 3, and 11. Since the two numbers are relatively prime, the possibilities are 9 and 11 or 1 and 99. The pair of 9 and 11 add up to 20 and their least common multiple is 99. So, 9 and 11 are the two numbers.
