Oh, dude, let me drop some math knowledge on you. So, a Prime number is a number greater than 1 that can only be divided by 1 and itself. Out of those options, 563 is the only prime number. The rest are just hanging out, being all divisible and stuff.

RafaThe only even prime is 2, so neither 234 nor 788 is prime. Since 1+2+3=6 is divisible by 3, the divisibility test for 3 says 123 can not be prime. If one of the options must be prime, then we know it is 563. Just to check:
563 is odd and not divisible by 3,5,7,11,13,17,19, or 23. Since it is not divisible by any primes less than its square root, we know that 563 is not divisible by any whole numbers other than itself and one and is hence prime.

What is the greatest common factor of 18 45 and 63?
Prime factorization of 18 = 2 x 3 x 3 Prime factorization of 45 = 3 x 3 x 5 Prime factorization of 63 = 3 x 3 x 7 It can be seen that 3 x 3 is the greatest number common in the factorization of 18, 45 and 63. So, GCF is 3 x 3 = 9.
