If a number cannot be factored it is a prime number.
No. It can be factored as 13*47.
no 48 is not a prime number. A prime number is a number that only have 1 and itself as factors.
When a number can only be factored by 1 and itself or cannot be factored at all it is considered prime.
composite
Yes.
53 is a prime number between 48 and 58
There is not one. A prime number has exactly two factors, 1 and itself. The only way that a prime number could be divisible by 48 is if 48 were a prime number, which it is not.
As a product of its prime factors: 5*5*7 = 175
All composite numbers can be expressed as unique products of prime numbers. This is known as a prime factorization.
