68 is a composite number because it has more than two factors and it is not a prime or a square number


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.


The sum of the prime numbers 2, 5, and 61 is 68.


No, 42 and 68 are not relatively prime. They have more than the number 1 as a common factor.


17 is prime and 68 is 17 times 4, so the number that can go into 17 and 68 is 17.


No it isn't. 68 can be divided by numbers other than itself and 1.



Because it is divisible by 2. A prime number can ONLY be divided by 1 and itself.

Prime factorization is the process of finding which prime numbers you need to multiply together to get your original number (in this case, 68).2 is the smallest prime number, so if you are trying to find the prime factorization of an even number (which we are), you should start by dividing the number by 2.so...68 ÷ 2 = 34so 2 is going to be the first prime number in our answer.34 is also an even number, so we can divide it again by 2.34 ÷ 2 = 17since we were able to divide by 2 a second time, 2 is also going to be the second number of our answer.Also, 17 is a prime number, so we can't break the number down any farther. That means 17 will be the third and final number in our answer.So according to the work we just did...2 x 2 x 17 = 68or to put it in simpler form..22 × 17 = 68


Prime factors of 68 are 22 x 17.


68 has two prime factors: 2 and 17.


Divide by 2 until you hit 17. 2 x 2 x 17 = 68


The prime factorization of 68 is 17 x 2 x 268 is composite. It is 2 x 2 x 17.


As a product of its prime factors: 2*2*17 = 68


nothing, because seventeen is a prime number.


Prime factors of 52 are 2 and 13 Prime factors of 68 are 2 and 17
