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!

Is 15 a deficient number?
Yes 15 is a deficient number because its factors add upp to less than the number itself,which is 15.
Why is 13 a deficient number?
Because all of its factors also known as 13 and 1 add up to be more than the number itself 13.
Is the number 10 a perfect number?
No. The factors of 10 other than 10 itself are 1, 2, and 5. These add up to 8, not 10.
Is 7 a composite number or prime?
Prime. It is only divisible by itself and one.
What is called when you add the same number to itself?
doubling
Why is 6 a perfect number?
A perfect number is an integer, the sum of whose integral factors, including 1, but excluding itself, is equal to itself. In other words, when the sum of a number's proper factors equals itself, it is called a perfect number. That means that if you add all of any given number's factors (including 1, but not itself), you get that number. 6 Factors: 1, 2, 3, 6 Sum of factors less than itself: 1 + 2 + 3 = 6 28 Factors: 1, 2, 4, 7, 14, 28 Sum of factors less than itself: 1 + 2 + 4 + 7 + 14 = 28
What is the number called when all its factors add up to twice the number?

Yes 15 is a deficient number because its factors add upp to less than the number itself,which is 15.
Why is15 a deficient number?
That means that the sum of the number's factors, less than the number itself, is less than the number in question - in this case, if you add the factors of 15 (except 15 itself, which is also a factor of 15), you get a total that is less than 15.
Is 38 a perfect number?
no it is not beacuse if u add all its factor which r 1,2,19 u get 22 and a perfect number has to be wgen u add up all the factors u get the number itself...

Why is 13 a deficient number?
Because all of its factors also known as 13 and 1 add up to be more than the number itself 13.
