They are all factors of 60
Numbers having 3 factors are 4 and the squares of all odd prime numbers (9, 25, 49, 121, etc.).
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
Calculate the least common multiple of the three numbers. Any multiple of that has all those numbers as factors.
