Prime Numbers. 1 isn't prime, 2 is. so is 3,5,7,11,13,17,19...
The largest known prime number is 17,425,170, although technically, there is no largest possible prime number. To this day, mathematicians are still searching for higher prime numbers.
As long as the other number is not a multiple of the prime number, the GCF will always be 1.
As of August 2017, the largest known prime number is 2^74,207,281 − 1, a number with 22,338,618digits.
The new prime number, 2 multiplied by itself 57,885,161times, less one, has 17,425,170 digits.
Roosevelt's Agriculture Secretary James Wilson gave the U.S. Forest Rangers the enduring directive to run the forests for "the greatest good of the greatest number in the long run."
M sub 39 is the largest prime number. I can't write it out because it is over 40,000 numbers long.
One is not considered a prime number, because a normal prime number only has two divisors, itself and one. But one only has one divisor- one and itself, which is also one. One is a special case, not prime, not composite.No, it is the multiplicative identity and neither prime or composite. There was a short period in history when some called it prime--but those years are long gone.
I'm sure there are more than 2 prime numbers that are 400 digits long.
Perhaps what you mean to ask "What is the next prime number above 53?". One cannot tell, as numbers are indeed infinite, what the highest prime number is. There is a team of scientists that, not too long ago, discovered a twelve-digit (I think twelve) prime number. Prime numbers, like numbers, are infinite and there is no way, therefore, to assess a 'highest' nor a 'lowest' numeral.
