The first three common multiples of XNUMX are XNUMX
the answer: XNUMX, XNUMX, XNUMX
The first three common multiples of 16 and 4 are 16, 32, and 48. The least common multiple of 16 and 4 is 16, which is the first multiple that appears in both numbers. The greatest common multiple of 16 and 4 is also 16, which is the greatest common factor that appears in both numbers. Since the greatest common multiple is equal to the least common multiple, this means that 16 is the only common multiple of both numbers.
