There are two numbers which fulfill this classification which are less than 30:1 + 2 + 3 = 61 + 2 + 4 + 7 + 14 = 28Perfect numbers can be calculated with the following formula:2n*(2(n+1)-1)For example, the first perfect number is: 21*(22-1) = 6The second perfect number is: 22*(23-1) = 28
Numbers between 1 and 30 that are even numbers?
Even numbers are integers that are divisible by 2. Between 1 and 30, the even numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30. These numbers can be obtained by starting from 2 and adding 2 successively until reaching 30.
How do you find perfect numbers below 30?
A perfect number is a whole number such that when you add up all of the factors less than that number, you get that number.There are only two perfect numbers less than 30. The first one is 6 since 1+2+3-6 next we see that 1 + 2 + 4 + 7 + 14=28 so 28 is the only other perfect number below 30.Euclid proved that 2p−1(2p−1) is an even perfect number whenever 2p−1 is prime.This works for 6 and 28 where p is a prime and is 2 and 3 respectively. Using this formula for p=5, the next perfect number is 24(25−1) = 496The next one is p = 7 where we have 26(27−1) = 8128.The next perfect number is 33550336 we get this with the prime 13.
