Except for 1, 2 and 7 do not have a lowest common factor. They lowest common multiple for 2 and 7 is 14.
you would have to make a factor tree for 8, 14, and 21. 8 equals 2*2*2. 14 equals 7*2 and 21 equals 7*3. Then you have to see what is the lowest number that they have in common. 8,14,21 do not have a number in commone so there isn't a common multiple.
The least common multiple of the numbers 8, 12 and 7 is 168.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 2, 7, and 9 is 126.
The Least Common Multiple (LCM) of 7 and 46 is 322.
Lowest common multiple of 2 and 7 is 14.
