First common multiples are also know as the least common multiples (LCM)
the answer is................
168
42 and 84
Since the lowest common multiple of 6 and 7 is 42, the multiples of 6 and 7 are multiples of 42. The first five are: 42 84 126 168 210
You multiply 6, 7, and 8 until all answers are the same. For example, the common multiples of 3 and 7 would be 21, because: 3,6,9,12,15,18,21 7,14,21 See how they both have the common multiples? Hope this helped!
42, 84, 126
The first multiple is the LCM of 6, 7 and 8. Then you find LCM*2 and LCM*3.
The First common multiple of 6 and 7 is 42 and the next common multiple is 84.
42 and 84
Since the lowest common multiple of 6 and 7 is 42, the multiples of 6 and 7 are multiples of 42. The first five are: 42 84 126 168 210
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
42, 84 and 126
42, 84, 126
The only common multiples of 6 & 7 up to 100 are 42 & 84.
The common multiples of 6, 7, and 8 are the multiples of its least common multiple, which is 168.The LCM of 6, 7, and 8 is 168.168, 336, 504 and so on.
You multiply 6, 7, and 8 until all answers are the same. For example, the common multiples of 3 and 7 would be 21, because: 3,6,9,12,15,18,21 7,14,21 See how they both have the common multiples? Hope this helped!
The first 6 multiples of 7 are: 7, 14, 21, 28, 35, and 42.
