161 is a prime number. It is the smallest positive integer greater than or equal to 2 and less than the square root of 7.
161 is a prime number. It is the smallest positive integer greater than or equal to 2 and less than the square root of 7.
The number of prime numbers is pretty much 1.2e. So, if we take 161 as a prime number, it is the smallest number greater than or equal to 2 and less than the square root of 7.
That’s all well and good. But does 161 count as a prime number? Well, yes and no. Prime numbers are definitely all about divisibility. For instance, 17 is a prime number. It is the smallest positive integer greater than or equal to 2 and less than the square root of 7. But 17 is also not prime because there are exactly 17 divisors to 17.
The only way to find out the prime number is to use some sort of approximation. To do this, we’d have to find the least rational number in the whole family and then go directly from this to the closest prime number. We can’t take our divisor, therefore, without a doubt, as a prime number. But even if we could take our divisor as an approximation we still wouldn’t find a prime number.
You can make a prime number by picking numbers that are divisible by two and greater than or equal to the square root of seven, but if you want to find a prime number using only rational numbers, you have to pick the squares root of two, which is 161. There are exactly three primes, 2, 3 and 7, which is the only case where this happens.
In other words, 161 is a prime number. Which means that you can’t pick 161 as your factorization (i.e. a divisor) because it’s not a prime number. There’s a problem with this though because we’re stuck playing the same game over and over again, which means that we can’t pick 161 as our divisor and therefore can’t find a prime number in this game.
If you want the game to end, you have to guess 161! which means that you can’t be sure of the first factor of 161, or you would have to think of a way to find a prime number (which is not the point of the game). That’s the thing about the game, the only way to be sure of the first factor of 161 is to play it over and over again, so we cant pick 161 as our factorization.
If you are trying to end the game, you have to pick 161. A prime number is simply a number that cannot be written as a composite of any odd number, so if you can find a number that is not prime, then you are guaranteed to end the game.
If you just want to see a number that is not a prime, then you probably want to go with a prime number because that’s the way most people have been programmed to play games. We know from the review in regards to a number that is not a prime, so we just pick another prime number that is not a prime (there are so many prime numbers in our game, so we must pick another prime number for the game).
