False. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. Every multiple of 5 is not a composite number, as 5 itself is a prime number with only two distinct positive divisors, 1 and 5.
45 is a composite since it factors are 5 and 9.
There are many, many more composite numbers than prime numbers. For example, beyond the number 3, every other number is composite, as it is divisible by 2. Following this, every number ending with a 5 other than 5 itself is composite, as it is divisible by 5, and every third odd number is divisble by 3. There are many complicated divisibility tests for numbers above 5.
Yes. Any multiple of 5 other than 5 itself is composite.Yes 105 is a composite number because it has more than two factors.
25 is not a prime number, it is a composite number, because it can be multiplied by 5 to get 25. A prime number can only be divisible by itself and 1.25 is a composite number like every number greater than 5 that ends with a 5.No, it is divisible by 5.
