5. And primes must be integers.

3 and 5 are co-prime. So every integer can be expressed as a linear combination of 3 and 5. For example, 17 = (-1)*3 + 4*5 Since any integer can, any rational number can. That leave irrationals, which cannot.
2 3 5 are prime numbers.

The prime numbers with square roots between 4 and 5 are 5 and 7.
Multiply the 4 smallest prime numbers... 2 X 3 X 5 X 7 = 210

71 is prime. 55 is not a prime number. Its positive integer factors are 11 and 5. The number 71, meanwhile, is prime, as it has no positive integer factors other than itself and 1.
2 3 5 are prime numbers.
A prime number is a positive integer that only has two factors. 2, 3, 5 and 7 are examples of prime numbers.

The prime numbers with square roots between 4 and 5 are 5 and 7.
Two numbers are relatively prime if their greatest common divisor (GCD) is 1. In other words, there is no positive integer greater than 1 that divides both of the numbers. For example, 7 and 12 are relatively prime, but 10 and 15 are not, as their GCD is 5.
Prime numbers : 2, 3, 5, 7 Composite numbers : 4, 6, 8, 9
3 and 5 are prime numbers whereas 4 is a composite number
Integer numbers : ...-5,-4,-3,-2,-1,0,1,2,3,4,5... Float numbers 1.25, 1.26 etc They are float numbers because its value can be altered after the point, which is based on an integer number.
