7 is a factor of 77 so it cannot be a prime. So it has to be composite.
It is composite since 7 x 11 is 77 and those are both primes. That is to say, it is the product of two primes and that makes it composite.
No, it is composite. Its factors are 1, 7, 11, 49, 77, 539.
86 is not a prime number, so is a composite.
No 168 is not a prime number it is a composite number
A prime number has exactly two factors, 1 and the number itself. You should find no other factors of a prime number. A composite number has *more* than two factors. Examples of prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 Examples of composite numbers: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33 Numbers that are neither prime nor composite: 0, 1 To test if a number is prime or not, try to find another number that divides it. For example, if I gave you 77... you should find that it is divisible by 7. 7 x 11 = 77 So 77 is not prime, it is COMPOSITE. But if I gave you 37, you can't find any other number (besides 1 and 37), that will divide into it evenly. So 37 is PRIME. And remember that 0 and 1 are exceptions. They aren't considered prime or composite.

77 is a composite number
A prime number is a number that is divisible only by 1 and itself; it has no other factors. A composite number is a number that is divisible by more than 2 numbers. The factors of 77 are 1, 7, 11, and 77. Therefore, 77 is a composite number.
The numbers, "77" is not a prime number - it can be evenly divided by 1, 7, 11, and 77.
77 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
It is a composite number.
Identify each number as prime, composite or neither: 1
As a product of its prime factors: 7*11 = 77
77 is a composite number because it has more than two factors.
77 is composite.
