No because they are both composite numbers

Yes. There are no common divisors other than 1.

The GCF of 243 and 256 is 1.

Yes. 256 is a power of 2 so its only factors are powers of 2. 315 is odd so no power of 2 can be a factor.

2 is the only prime factor of 256.

Prime factors of 256=2x2x2x2x2x2x2x2 (or 28)

The prime factors of 256 are 2x2x2x2x2x2x2x2 (or 28).

The GCF of 243, 256, and 343 is 1. 243 = 3^5 256 = 2^8 So the first two have a GCF of 1. Adding 343 = 7^3 to the list cannot increase the GCF so it must remain 1.

No, they are not relatively prime.

IS 243 PRIME OR COMPOSITE

The only prime factor of 256 is: 2

It can be. 34 is relatively prime to 35. 34 is not relatively prime to 40.

25 is relatively prime with 36. 25 is not relatively prime with 35.

35 = 243

2^8 = 256

256 is not prime. 256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
