What is the Perfect number and what is the perfect number after 28?

A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496


Is 28 a prime explain how?

No since it is an even number it has 2 as a factor. If the factors are the number itself and 1 it is prime. If there are more factors it is not. 28 has many more factors.28=22 x7So 2 and 4 and 7 are all factors as is 14.


What is another number between 20 to 30 that has the same number of factors as 28?

20 and 28 both have six factors.


Is 42 a perfect number?

Use the definition of a perfect number! Add the factors; if the sum of all the factors (excluding the number itself) is equal to the number, it is a perfect number, otherwise it isn't. (Actually, the only perfect numbers less than 100 are 6, and 28.)Use the definition of a perfect number!

Why is 28 a perfect number?

A number is perfect if all it's factors (barring itself) sum to make the original number. In this case, the factors of 28 are 1,2,4,7 and 14. Added up, these equal 28. Thus, 28 is a perfect number.

How is 28 the perfect number?

First of all, to know if a number is abundant, deficient, or perfect, you need to know all the factors of your given number. The factors of 28 are 1,2,4,7,14, and 28. Add your proper factors -or the factors except itself- and determine if the sum of the proper factors is below (deficient), above (abundant), or the exact same amount (perfect). In this case, if you add the proper factors, it equals exactly 28. Because it is exact, it is perfect! =)


What number goes into 28?

7*4 A number which can go into a number is called a factor. factors of 28 = 1, 2, 4, 7, 14, 28 to find the factors of a certain number, divide this number by numbers from 1 to whatever the number is, and if the answer is an integer (whole number), it is a factor, e.g. 28: 28 divided by 4=7 therefore, both 4 and 7 are factors of 28 28 divided by 14=2 therefore 14 and 2 are factors of 28 28 divided by 28=1 therefore 28 and 1 are factors of 28 therefore, factors of 28 are 1, 28, 2, 14, 4, 7
