43, 23 and 2
A prime number is one that only has factors of 1 and its self (3 is a prime number because you can only multiply 1 and 3 to get it). Since you can multiply 1 and 68, 2 and 34 or 4 and 17 to get 68 it is not a prime number.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 68 is composite.
68 = 22 x 17
This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.
17 is a prime number but 68 is Composite.
The numbers 71, 73 and 79 are prime.
The sum of the prime numbers 2, 5, and 61 is 68.
To find the prime factors of 68 start with any factor pair of 68 and keep factoring the composite numbers until all factors are prime: 2 x 34 2 x 2 x 17
No it isn't. 68 can be divided by numbers other than itself and 1.
59 and 61.
2 x 2 x 17 = 68 or 22 x 17 = 68
How about: 2*2*17 = 68 as a product of its prime factors

68
A prime number is one that only has factors of 1 and its self (3 is a prime number because you can only multiply 1 and 3 to get it). Since you can multiply 1 and 68, 2 and 34 or 4 and 17 to get 68 it is not a prime number.
Oh, isn't that a happy little question! Let's see, the prime numbers between 30 and 40 are 31, 37. So, if we add them together, we get 68. Just remember, there are no mistakes, only happy accidents in math and painting!
