It is 18.
To calculate the mean of the numbers 56, 77, 68, 63, 69, 68, 80, 71, and 63, first sum them: 56 + 77 + 68 + 63 + 69 + 68 + 80 + 71 + 63 = 616. Then, divide the total by the number of values, which is 9. Thus, the mean is 616 ÷ 9 = 68.44.
There are three prime numbers between 62 and 72: 61, 67, and 71. Prime numbers are those greater than 1 that have no divisors other than 1 and themselves. In this range, 63, 64, 65, 66, 68, 69, and 70 are not prime. Therefore, the primes are 67 and 71.
The common factor of 63 and 71 is and 1.
71 - 8= 63
21 is a factor of 63 (21 * 3 = 63).71 is a prime number.Since 71 has no common factors with 63, they must be multiplied together to find their least common multiple.Thus, the least common multiple (LCM) of 21, 63 and 71 is 63 * 71 = 4473.
It is 71-8 = 63.

The odd numbers between 60 and 75 are: 61, 63, 65, 67, 69, 71, 73
The prime numbers between 65 and 75 are: 67, 71 and 73

Median means average, and range is the range of numbers in a group. For example, the range is from 52 to 71. I don't know what a mode is.
There are 5 such numbers. The smallest is 63. The remaining numbers are 67, 71, 75, and 79
