That's an infinite list that starts off with 56, 112, 168 and so on.
The LCM of the given three numbers is 168
The prime numbers from 1 to 8 are 2, 3, 5 and 7.
7 and 8
The LCM of the numbers 4, 7, and 8 is 56.
You add all the numbers. Then you divide the numbers by the number that indicates how many numbers you have. For example, the average of 7, 8, and 9 is (7 + 8 + 9) / 3. Here I am dividing by three because there are three numbers.
There are infinite numbers, but a fine example is just 7*8*10 or 560
These numbers all go into 56 evenly: 1, 2, 4, 7, 8, 14, 28, 56.
The LCM of the given three numbers is 168
The only number which will go evenly into all of them is 1.
1,2,4,7,8,14,28,54
The prime numbers from 1 to 8 are 2, 3, 5 and 7.
7 and 8
Only the number 1.
They are all positive integers.
The number 7 is not divisible by 2, so it is odd. The number 8 is divisible by 2, just as all even numbers are. It is an even number.
Take the sum of the numbers divided by the number of numbers. Mean = (7+8+8+2+10+8+7)/7 = 7.14
To find the average of a number, first you add all the numbers that you want to average. Then you need to divide the sum of the numbers by the number of numbers there were. So if a set of numbers is 3, 5, 7, 1, 4, 7, 8 The equation would be 3+5+7+1+4+7+8=35/7(for the 7 numbers)=5
