There is no "greatest common multiple" of any two numbers. Whatever their product is, it can be multiplied by any positive integer to yield an even greater number that is also a multiple of the first two. Thus, the number of multiples is infinite.

lots of numbers. 2and3, 4and5, 7and13, basically if the numbers that the difference is 1, the GCF(Greatest Common Factor) If they don't share any factors,(except 1)the GCF is 1
There is an infinite number of common multiples for 3 and 15. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 3 and 15 is 15.
19 and 7 are both prime numbers, so that cannot share any factors, the lowest common multiple will therefore be arrived at by multiplying 19 by 7 = 133
The greatest common denominator of any set of denominators is infinite.
Any multiple of 8.
