No, it is not true.
13 is a prime number and 39 isint a prime number
False - 2 + 11 = 13.
A good way to remember prime numbers from 1 to 100: Take any number. If it is only divisible by 1 and itself, then it is a prime number. If it is divisible by any other numbers, then it is not a prime number. Example: 13. You can only get 13 by multiplying: 1 x 13, and 13 can only be divided by 13...13/13 = 1...or 1....13/1=13. So 13 IS a Prime number. Example 14. You can get 14 by multiplying: 1x14, 2x7, and you can divide 14 by 2 to get 7, or by 7 to get 2, so 14 is NOT a Prime number, since numbers other than itself and 1 are able to be divided into it to get whole numbers. This test will hold true for any prime number.
13 is a prime number13 is a prime number, because there are no two numbers that multiply to get 13.It is a prime number because no number can go into it or be multiplied and the answer be 13.Only two numbers go into 13.The two numbers:1;13One and thirteen (itself)1 is neither prime or composite.So concluding, 13 is a prime number.
Yes. 169/13=13 13 is a prime number.
11 and 13 are both prime numbers.
Not always true because 2 times 13 = 26 which is an even number
13 is a prime number because it will only divide exactly by 1 or 13.
Prime number of 13 is 13 Prime numbers of 26 are 2 and 13 Prime numbers of 65 are 5 and 13 LCM = 2*5*13 =130
17
They are 13 and 19 which are prime numbers
It can be. Since 13 is a prime number, it is relatively prime to all other numbers except for multiples of 13.
