The sum of the proper factors of 4 is less than 4 List all the numbers through 50 for which the sum of its proper factors is one less than the number itself?
The numbers for which the sum of its proper factors is 1 less than the number is the powers of 2; less than 50 these are: 2, 4, 8, 16 & 32.
How do you identify prime numbers less than 100?
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
What 3 numbers less than 50 have exactly 2 factors?
Every prime number has exactly two factors. They are '1' and the number itself. There are 15 prime numbers less than 50. A few of them are 2, 3, 5, 7, 11, 13, and 47.
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.

Is 76 an abundant deficient or perfect?
Abundant, deficient and perfect numbers are determined by the sum of the proper divisors (or factors) of a number, which excludes the number itself. The factors of 76 are : 1,2,4,19,38,76 . . . after excluding the number itself the sum of the proper divisors is :- 1+2+4+19+38= 64 Deficient numbers occur when the sum of the proper divisors is less than the number itself. As 64 is less that 76 then it is deficient.
How do you get the prime numbers less than 16?
You test them, one at a time, to weed out any that has factors besides ' 1 ' and itself. When you do that, you find that 2, 3, 5, 7, 11, and 13 are prime numbers.
How can you determine whether the LCM of two numbers is the product of the numbers or is less than the product of the numbers explain?
If the two numbers have no common factors other than 1, the LCM will be their product. If there are other common factors, the LCM will be less.
What is special about numbers less than fifty that have less than three factors?
They all are prime numbers except 1
