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.
It is prime
86 is not a prime number, so is a composite.
No, it is composite. Its factors are 1, 7, 11, 49, 77, 539.
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.
