Question

prime number is only divisible by 1 and itself. ... No other whole numbers can multiply together to make 11. 15 is not a prime number because the factors of 15 are 1, 3, 5 and15 ( ). 15 has more than 2 factors, so it is not a prime number. true or false​

Answer 1

15 is not a prime number - True

This is because 15 has other factors than 1 and 15, 3 and 5. Because it has other factors, it is not a prime number. An example of a prime number would be 7, 5, or 11, which are prime numbers because their only factor is 1 and itself.

Hope this helps!! :)
