As a product of its prime factors: 7*31 = 217
Lets see if 217 is a prime or composite number. 15 times 15 is 225, so we will try the first prime numbers up to 15. They are 2, 3, 5, 7, 11, and 13. Will 2 go into 217? No 7 is odd. Will 3 go into 217. If we add the integers, they add up to 10. 3 does not go into 10. Will 5 go into 217. No. It does not end in a 0 or a 5. Will 7 go into 217. Lets see. Will 7 go into 21? Yes it goes in an even number of times. How about that. Will seven go into 7. Yes it goes in an even number of times. You can show the math.
1519 is not a prime number. Its positive integer factors are 1, 7, 31, 49, 217, 1519.
217 = 7 * 31
7 x 31 = 217
217 isn't prime. It's factors are 1,7,31 and 217.
217 is not a prime number. 7 and 31 are factors of 217 besides one and itself.
217 = 7x31 and both of those are primes for that is its prime factorization! Dr. Chuck
