They are: 2+11+43 = 56
To find the prime numbers of 56, start with two numbers that when multiplied together equal 56. For example: 2 x 28 = 56. Two is prime, but 28 is composite, so it needs to be factored. 2 x 2 x 14 = 56. Now, 14 is prime, so factor it. 2 x 2 x 2 x 7 = 56. All the factors are now prime, so the prime factors are 2 x 2 x 2 x 7.
