What is the largest prime factor?

A prime number is a positive integer, excluding 1, with no divisors other than 1 and itself. According to Euclid’s theorem there are infinitely many prime numbers, so there is no largest prime.

How do you find the largest prime factor?

Factors are numbers that completely divide a particular number to get zero as a remainder. For example, if we look at the number 6 , it has four factors: 1 , 2 , 3 , 6 . However, of these factors, 2 and 3 are prime numbers. As 3 is greater than 2 , 3 is said to be the largest prime factor of number 6 .

What is the largest prime factor of 489652784103?

We can see it is divisible by 3.

    What is the largest factor?

    The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators.
