No 16 is deficient.12 and 18 are abundant.


Is 36 a abundant deficient or perfect number?

The proper factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18. Their sum is: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 18 = 55. As their sum (55) is greater than 36, the number 36 is an abundant number.


Is 18 a perfect number?

No 18 is not. It is a abundant number.


What are the Math terms abundant perfect and deficient?

They refer to the sum of a number's proper divisors, defined here as all of the factors except the number itself.a perfect number equals the sum of its proper divisorsa deficient number is greater than the sum of its proper divisorsan abundant number is less than the sum of its proper divisors


Is the number 18 deficient?

A deficient number is a number for which the sum of its positive integer factors (other than itself) is less than itself. The sum of the factors of 18 is 1 + 2 + 3 + 6 + 9 = 21. Since 21 is greater than 18, 18 is an abundant number.


Is 72 a abundant number or deficient number?

72 is an abundant number because the sum of its positive divisors, not including 72 itself, is larger than 72. Positive divisors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 18 + 24 + 36 = 123 > 72 (if an integer is larger than the sum of its positive divisors , not including the integer itself, then that integer is called a deficient number, such as prime or power of prime numbers or numbers like 10 are).


Is the number 18 abundant?

An Abundant Number is one that the factors (other than itself) add up to more than the number. 18 factors into [2 3 3] so the factor list is {1 2 3 6 9 18} and the sum of the rest is 21. Since 21 is greater than 18, it is an abundant number.Yes 18 is an abundant number because if you add all of it's factors (1,2,3,6,9,) together the sum is 21.Definition of Abundant- a number that is less the sum of it's factors or integers


Determine whether the number is abundant or deficient number 72?

72 is an abundant number because the sum of its positive divisors, not including 72 itself, is larger than 72. Positive divisors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 18 + 24 + 36 = 123 > 72 (if an integer is larger than the sum of its positive divisors , not including the integer itself, then that integer is called a deficient number, such as prime or power of prime numbers or numbers like 10 are).


What least number multiply to 18 to make it perfect square?

It is 2 times 18 = 36 which is a perfect square number because 6 time 6 = 36


Is 18 a square number why or why not?

It is a square number but not a perfect square. The nearest perfect squares, on either side, are 4^2 = 16 and 5^2 = 25. Since there is no integer between 4 and 5 and the square is a strictly monotonic function, 18 cannot be a perfect square.


What least number must be added to 5607 to make the sum a perfect square find theperfect square of its square root?

5607 + 18 = 5625, a perfect square. The perfect square of a square root is the number you started with.
