    Adding 1 to a random number changes all the factors of that number.
    48= 2*2*2*2*3
    Like 49=7*7.
    In the light of this information, we know that if we start from 1 and multiply the numbers consecutively and add 1, the resulting number is not divided by any of the previous multipliers.
    that is, if we add 1 consecutively to infinity, we can get a prime number at infinity.
    in an other saying
    forever! +1 is definitely a prime number. #math #maths #mathematics #primenumbers

      If a number is prime only 1 X (the number) works.
      So with 3. You can only do 1 x 3 meaning it’s prime
      But with 8. You can do 1 x 8 but also 4 x 2. Meaning it’s not prime because there are more multiplications that can equal the number.

    @JulianHotaling 10 месяцев назад

    Question Primes are primes whose index numbers are a prime; if all further reductions of that index number are as well, it is an Endogenous Prime. Candid Primes, the digits of the prime added up are a Prime, and all further reductions as well. Feral Primes are both Endogenous and Candid. Magnificent Primes are oftern called Primeth-recurrence Primes, 3,5,11, 31, 127. etc.... The "infinite" sum of the reciprocals all Primes is 33; the error is made perhaps due to the false belief that there are numbers greater than 10^77, or smaller than its reciprocal. Such numbers are called Malevolent Numbers, and should not be recognized. Neither should an imaginary square root of -1 be. The sum of the Harmonic Series hasn't more than 11 digits, reason for the error is the same...

    can someone explain why any of this matters in the real world like okay you now know what a prime and composite number is now what is the point of knowing that 2 is a prime number because the factors are 1 and 2 and them multiplied together make up the number 2? Is there like some hidden magic that we learn after knowing this about numbers? Who cares about numbers?! and how can u assume 5,462 is composite just because u see the 2 at the end u take that information of the 2 at the end and then jump and say its composite / even HOW?? just because u see the 2?? omg I hate math ya u lost me on 5) screw this. because u see the 2 u know it has to be even/composite because the 2 is at the end i guess? omg i hate numbers

    Why not 1.5 x2 = 3. Sorry but I'm terrible at math. When we talk of factors we have to use whole numbers??

    My question; why did my teachers not just say this? I couldnt make sense of the way they "taught" this! This and the Lcd!
