Answer 2

Is 119 A Prime Number

Answer 3

119 = 7×17

Answer 4

you can figure it out pretty quickly. To see if a number is prime, you only need to check if it is divisible by the numbers up to its square root. In this case the square root is between 10 and 11
(because we know 10^2 = 100 and 11^2= 121) so we only have to check the numbers 2 through 10. 119 is odd, so it won't be divisible by any even number, so that eliminates 2,4,6,8. It doesn't end in 5 or 0, so that eliminates 5. If we add 1+1+9 it comes to 11, which is not divisible by 3, so that eliminates 3 and 9. (If you add the digits in a number and the result is divisible by 3, then the original number is divisible by 3.)
So all you really have to check is 7! Sure enough, 7x17=119.

Answer 5

No.119 = 17 * 7 a prime # has only 2 factors : 1 and itself.

Answer 6

as the others said ... no
one of the answers above told you how to figure it out... I would simplify the work a little more by saying that you only had to test prime numbers below 11. Skip 1, 2, 3 for the reasons already given. Skip 4 because 4 is not prime (and if 4 would have worked, so would 2). Skip 5 as already said. Skip 6 because it is not prime (if 6 would have gone into 119, so would 2 and 3, its factors). 7 as we now know, is a factor of 119. skip 8, 9, and 10 because they are not prime.

So when factoring just do primes:
1,2,3,5,7,11,13,17,19, 23,29,31,37,41,43,47, 53,59,61,67,71, 73,79,83,89,97 (that would take you up to 10,000 (100 x 100)

Answer 7

I wouldn't have known for when I went to school I do not have any knowledge of us ever playing around with this subject. We left prime to paint as in a prime coat.

People here tell you that a prime number can only be divided by 1 and itself. Every number can be divided by 1 and itself.

So if they tell you 119÷7=17 and that 17x7=119; then I will join in on it. Heck if I would disagree.

Answer 8

no, 7 x 17 = 119. 119 is not a prime number. But turn it around, 911 is a prime number.
