A Prime number has no factors other than 1 and itself. Each multiple of fifteen includes 3, 5, and 15 among its factors.
It is 19
No... Every whole number that ends with a 5 includes 5 as a factor (is a multiple of 5).
15 is a factor of 45, but it is not a prime number.
Prime factor each number. Use each prime factor the most it was used in any one number. 15=3x5 25=5x5 30=2x3x5 2x3x5x5=150
2 is a prime number and 15 is a composite number.
It is 19
15 is one possible answer.
No... Every whole number that ends with a 5 includes 5 as a factor (is a multiple of 5).
None of them are multiples of 15. The be a multiple of 15, a number must have both the prime factors 3 and 5. None of them have a prime factor of 5, thus none can be a multiple of 15.
Because fifteen is a compound number. That is it is a multiple of 5 & 3 .
3*5 = 15 in prime numbers
There is no LCM of a single number. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
15 is a factor of 45, but it is not a prime number.

2 is a prime number and 15 is a composite number.
3 and 5 are Prime Factors of 15 (3x5=15).
Number 17 is but 15 isn't as 5x3 isn't a prime number
