How do we know that 1 is a prime number?
Mathematicians define a prime number as one with exactly two factors. 1 does not qualify.
What is the smallest number with 3 different prime factors?
The number 6. Its prime factors are 1,2 & 3 * * * * * Most mathematicians would argue that the correct answer is 2*3*5 = 30 on the grounds that 1 is NOT a prime.
Is 2 a prime number?
2 is a prime number because it is only divisible by 1 and itself.Ex:1*2=2It is the only even prime number and the smallest prime number!Yes and 2 is the only even prime number
What is the probability of getting a prime number when you roll a dice?
On a standard die, 2:1 in favour. This would be correct if 1 and 2 are accepted as prime numbers, which is allowed by some mathematicians and theories though not by all. ---- Having worked it out myself, I believe there is actually an even probability: Prime numbers: * 2 * 3 * 5 Not-prime numbers: * 1 * 4 * 6
Is 1 the lowest prime number?
