Yes. 25 is a multiple of 5 and the number 5 is a prime number.
The only prime multiple of 5 is 5.
5, which is the only prime number which is a multiple of 5!
The only prime factor of 4 is 2. No prime number is a multiple of 5.
Since 5 is a prime number, then any number, which is not a multiple of 5, is relatively prime with the number 5. You can determine if a number is a multiple of 5, by looking at the ones place digit. If it is a 0 or 5, and the number itself is not zero, then the number is a multiple of 5.
5 and 7 are both prime number so their LCM is their multiple, viz 5*7 = 35.35
GCF of a prime number and a composite number is 1 if the composite number is not a multiple of the prime number. Here, 5 is a prime number and 108 is a composite number(not the multiple of 5). Therefore GCF of 108 and 5 is 1.
No, it is a multiple of 5.
No. 5 is a multiple of it.
If the GCF of two numbers is 1, their LCM will be their product. Such numbers are called relatively prime, or co-prime. Any two prime numbers (like 3 and 5) will be that way, but the numbers don't have to be prime (like 4 and 9).
One two digit number that is not prime and is not a multiple of 2, 3, or 5 is 49. Another such number is 91.
A prime multiple is when a number is expressed as the product of its prime factors as for example: 2*3*5*7 = 210
