To find the average of a set of numbers, you add up all the numbers and then divide by the total count of numbers. In this case, the sum of 1242, 87, 512, and 169810 is 171651. Since there are 4 numbers in the set, you divide the sum by 4 to get the average, which is 42912.75.
1, 2, 4, 5, 10, and 20 divide evenly into 20.

2 and 60 will divide evenly into 120.
These are the numbers that divide into 28 evenly: 1, 2, 4, 7, 14, 28.
1, 2, 4, 5, 10, and 20 divide evenly into 20.
They are called factors or divisors.
divisors
To determine if 1242 is divisible by 23, you would perform the division 1242 รท 23. The quotient is approximately 54.08696. Since the quotient is not a whole number, 1242 is not evenly divisible by 23.
The greatest common factor of these numbers is 1. If it were a composite number, we could say that that number, and all the numbers that divide it evenly, divide these numbers evenly. However, these numbers are relatively prime-that is, the only factor they share is 1.
