A common multiple of two integers 'x' and 'y', are the multiples of 'x' which are also multiples of 'y'.For your example, because 12 is itself a multiple of 4, ALL multiples of 12 are common multiples of 4 and 12.To prove my point, I will list out the multiples of both 4 and 12:multiples of 4:4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,96, 100...multiples of 12:12,24,36,48,60,72,84,96...You can see here that every multiple of 12, is also a multiple of 4, thus all multiples of 12 are common multiples for 4 and 12.Also..a quick easy list:12,24,36,48,60,72,84,96and if you didn't read above, because 12 is a multiple of for, all multiples of 12 are a multiple of 4 .. simple!
