Who was the mathematician who discovered the largest prime number that exists?

It has been proven that there is no largest prime number. You can find a list of the largest KNOWN prime numbers here: http://en.wikipedia.org/wiki/Largest_known_prime_number

How do you find the largest prime factor of a number?

Suppose you have a number N and you want to find its largest prime factor. It is probably easiest to start at the bottom.Find the smallest prime factor, p.Find its factor pair = N/p.If the second number (= N/p) is a prime, then it is the largest prime factor.if not, replace N by N/p and go back to the top.

How can you prove there is no largest prime number?

No. No matter how large of an example you choose, someone always can find a larger number (of any kind), because the upper range of number is infinite. If you take all the known prime numbers and multiply them together, then add 1 to the result, you will have a number that is not divisible by any of the known prime numbers. This number will either be prime or have prime factors that were not previously known. So, in this way, you can always find a new prime number or a number that is a multiple of new prime numbers. If the known prime numbers include all the prime numbers up to the largest known, the new ones must be larger.

How do you find the largest prime factor of 100?

Find them all. Pick the largest one. 2 x 2 x 5 x 5 = 100 The largest prime factor of 100 is 5.

How do you find 1000 percent of a number?

What is the greatest common factor of 333 and 1000?

The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 333 and 1000, you can use prime factorization. The prime factorization of 333 is 3 x 3 x 37, and the prime factorization of 1000 is 2 x 2 x 2 x 5 x 5 x 5. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 1 x 1 x 1 = 1. Therefore, the GCF of 333 and 1000 is 1.

How to get largest prime factor?

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210. The largest of those numbers is the largest prime factor.

How can you prove there is no largest prime number?
