To find the average of a set of numbers, you add all the numbers together and then divide by the total count of numbers. In this case, the sum of 16, 18, 14, and 12 is 60. Since there are four numbers in the set, you divide 60 by 4 to get an average of 15.
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two. Ex. (14, 16, 16, 20, 21, 23) The median is 18. In any given set, the mode is the number that appears most often. If no number appears more frequently than any other, there is no mode. Ex. (14, 16, 16, 20, 21, 23) The mode is 16. In any given set, the range is the smallest number subtracted from the largest number. Ex. (14, 16, 16, 20, 21, 23) 23 - 14 = 9 The range is 9. In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (14, 16, 16, 20, 21, 23) 14 + 16 + 16 + 20 + 21 + 23 = 110 There are 6 numbers in this set. 110/6 = 18 and 1/3 The mean is 18 and 1/3.

Range = Maximum - Minimum = 20 - 8 = 12.
The set of odd natural numbers less than 18 includes the numbers: 1, 3, 5, 7, 9, 11, 13, 15, and 17. This set can be expressed as {1, 3, 5, 7, 9, 11, 13, 15, 17}. These numbers are all the odd integers that fall within the range of natural numbers up to 18.
That appears to be one big number. I guess there are supposed to be spaces to separate the numbers. Looking at the number, it looks [to me] like the set of numbers is most likely to be {15, 16, 19, 14, 20, 18, 18, 18}. range = highest_number - lowest_number = 20 - 14 = 6.
We can't answer that without knowing the set of numbers.

18, 23, 10, 39, 22, 17, 16, 15 Mean = (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)/8 = 20 Lowest Number in set is 10 Highest Number in set is 39 Range = (39 - 10) = 29
One possibility: 5, 6, 7, 7, 7, 12, 12, 13, 14, 15, 16, 18
Range = Maximum - Minimum = 20 - 8 = 12.
The LCM is 144. Any multiple of 144 will also be a multiple of 16 and 18.
The set of odd natural numbers less than 18 includes the numbers: 1, 3, 5, 7, 9, 11, 13, 15, and 17. This set can be expressed as {1, 3, 5, 7, 9, 11, 13, 15, 17}. These numbers are all the odd integers that fall within the range of natural numbers up to 18.
4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20 are composite. The other numbers in that range are prime.
The GCF of 16, 18, and 30 is 2. The GCF of the set can't be any greater than the smallest difference between two numbers in the set. The difference between 16 and 18 is 2, and so that's the highest possible GCF. Noting that each number in the set is even, we then know that the GCF is, in fact, 2.The GCF is 2.
