Both are composite.
Yes. A composite number is a number that is not prime. In the case of 225, it can be broken down to 5 * 5 * 3 * 3, and is thus composite.

The GCF is 15.
900 is not prime. 900 = 2 * 2 * 3 * 3 * 5 * 5
4, composite. 67, prime.
225 is composite.
225 is composite. The last digit is 5, so it is divisible by 5. Therefore it is composite. In fact, it is 15 squared. In contrast, a prime number is a number that is divisible only by 1 and itself; it has no other factors. The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225. Therefore, 225 is a composite number.
Yes. A composite number is a number that is not prime. In the case of 225, it can be broken down to 5 * 5 * 3 * 3, and is thus composite.
65, 77, 78 and 315
As a product of its prime factors: 3*3*5*7 = 315
225 is a composite number. This is because composite numbers are any number that has more than two factors (one and itself). Therefore, since there are many factors of 225 besides one and itself such as 3, 5, and 9, that makes it a composite number.
No, 315 is not a prime number. It is called a composite number. A prime number is a number that is only divisible by one and itself. For example, the number 11 is a prime number since only 11 and 1 go into 11 evenly. 315 is divisible by other numbers (ex: it is divisible by 5)
The GCF is 45.
The greatest common factor of 315 and 225 is 45.
225 is a composite number because it is divisible by at least one number other than itself and 1.
