Is 77 prime or composite?

Explanation: A prime number is one which does not have any factor other than 1 and itself. A composite number is one which also has factors other than 1 and itself. As 77=7×11 , it has two factors 7 and 11 (other than 1 and 77 ) and as such it is a composite number.

Is 72 a prime or a composite?

If the factors of 72 are only 72 and 1, then we know that 72 is a prime number. Otherwise, 72 is a composite number. To explain better, if 72 is only divisible by 1 and 72, then it is a prime number, and if 72 is divisible by more than 72 and 1, then it is a composite number.

Is 75 a perfect square?

Is 75 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 75 is about 8.660. Thus, the square root of 75 is not an integer, and therefore 75 is not a square number.

Is 77 a perfect number?

For 77 to be a prime number, it would have been required that 77 has only two divisors, i.e., itself and 1. However, 77 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 77 = 7 x 11, where 7 and 11 are both prime numbers.

Is 72 a perfect number?

For 72, the answer is: No, 72 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 72) is as follows: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72. For 72 to be a prime number, it would have been required that 72 has only two divisors, i.e., itself and 1.

What are the factors of 75?

75 = 1 x 75, 3 x 25, or 5 x 15. Factors of 75: 1, 3, 5, 15, 25, 75. Prime factorization: 75 = 3 x 5 x 5, which can also be written 75 = 3 x 5².

Is 73 prime or composite?

When a number has more than two factors it is called a composite number.
