Why is 74 not a perfect number?
A perfect number is defined as a positive integer that is equal to the sum of its proper divisors, excluding itself. For 74, the proper divisors are 1, 2, 37, and their sum is 1 + 2 + 37 = 40, which is not equal to 74. Therefore, 74 does not meet the criteria to be classified as a perfect number.
Why 21 is not a perfect number?
First, you want to know the definition of a perfect number: A perfect number is an integer which is equal to the sum of all its positive integer divisors that are less than itself. Example: The positive integer divisors of 6, less than 6, are 1, 2, and 3. The sum of those divisors is 1 + 2 + 3 = 6. Therefore, 6 is a perfect number. Now, 21 does not meet this definition and therefore is not a perfect number. Let's try it. There are three positive divisors of 21, namely, 1, 3, and 7, that are less than 21, itself. (There are no others.) But the sum of these divisors is 1 + 3 + 7 = 11, which is not equal to 21. Therefore, we confirm that 21 is not a perfect number.
When is the absolute value of a number equal ti itself?
When the number is greater than or equal to zero. e.g. l 5 l = 5
Is 36 perfect?
No, 36 is not a perfect number. A perfect number is defined as a positive integer that is equal to the sum of its proper divisors (excluding itself). For 36, the proper divisors are 1, 2, 3, 4, 6, 9, and 12, which sum to 37, not 36. The smallest perfect number is 6.
What is 29.47 equals?
This number is equal to itself, and to no other number.This number is equal to itself, and to no other number.This number is equal to itself, and to no other number.This number is equal to itself, and to no other number.
What is a perfect number and give an example of one?
A perfect number is equal to the sum of its proper divisors (the factors excluding the number itself.) 6 is a perfect number. Its proper divisors are 1, 2 and 3.
What is the term for equal to the sum of its proper factors?
A perfect number is the term for a number that is equal to the sum of its proper divisors. Be careful not to confuse that with proper factors. Proper divisors include 1 but not the number itself. Proper factors don't include either I or the original number.
What is an amicable number?
An amicable number is one of a pair of numbers which have the property that the sum of the divisors of each, excluding itself, is equal to the other number.
How is 8589869056 a perfect number?
8589869056 is not a perfect number. A perfect number is a positive integer that is equal to the sum of its proper divisors, excluding itself. In the case of 8589869056, the sum of its proper divisors is less than the number itself, making it an abundant number, not a perfect number.
What are the perfection numbers?
A number is considered perfect if it is equal to the sum of all its positive factors/divisors, excluding itself. These are the first few perfect numbers: * 6 * 28 * 496 * 8128 * 33550336 * 8589869056A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. An example 1+2+3=6 and 1x2x3=6
Why 21 is not a perfect number?

Example: The positive integer divisors of 6, less than 6, are 1, 2, and 3. The sum of those divisors is 1 + 2 + 3 = 6. Therefore, 6 is a perfect number. Now, 21 does not meet this definition and therefore is not a perfect number. Let's try it. There are three positive divisors of 21, namely, 1, 3, and 7, that are less than 21, itself.

When is the absolute value of a number equal ti itself?
When the number is greater than or equal to zero. e.g. l 5 l = 5
Why are perfect numbers perfect?
A perfect number is only classified as a perfect number because all of its proper divisors add up to itself. For example, the proper divisors of six are one, two and three. Those numbers added together equal six. Therefore, six is a perfect number.
Is 36 perfect?
No, 36 is not a perfect number. A perfect number is defined as a positive integer that is equal to the sum of its proper divisors (excluding itself). For 36, the proper divisors are 1, 2, 3, 4, 6, 9, and 12, which sum to 37, not 36. The smallest perfect number is 6.
