What is the greatest even number that is a prime number and why?
A prime number is any number that only has one and itself as factors. By definition even numbers have a factor of two. Therefore the greatest and only even number that is prime is the number 2.
What is the greatest common factor of 2 or more prime numbers?
As the numbers are all prime, the only factors each of them has are 1 and the number itself. Therefore the greatest, and only, common factor of two of more prime numbers is 1.
What has prime faccorisation got to do with least common multiple and greatest common factor?
Prime factorization tells you what prime numbers multiply to get the number. You can see which numbers that number is divisible by to get the multiples and factors.
Will you get the same number of factors if you multiply a prime number and itself?
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
What numbers has only 2 factors?
Any prime number, a prime number is a number of which the only factors are it and itself.
What numbers have the greatest common factors of one?
Co-prime numbers, relatively prime numbers and any set of prime numbers.
What is the difference between factors of a number and prime factors of a number?
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
What is the greatest whole number with no more than six factors?
A prime number has only two factors. That is, it can only divide evenly by 1 and itself. It is known that there are an infinite number of prime numbers. Thus prime numbers continue up to infinitely large amounts. Therefore it makes no sense to ask what the "greatest number with no more than 6 factors" is. It's the same as asking what the biggest number is!
Why is 11 the next greatest prime number after 7?
11 is the next greatest prime number after 7 because 8, 9 and 10 are all composite numbers meaning these numbers have other factors aside from 1 and itself.
What is the greatest common factor of 13 and 51?
The greatest common factor of 13 and 51 is 1.The common factors of 13 and 51 are only the number 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 13 are 1 and 13.The factors of 51 are 1, 3, 17, and 51.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor.The prime factors of 13 are 1 and 13.The prime factors of 51 are 3 and 17.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
How do you figure out prime numbers not knowing there factors?
But you do know the factors of prime numbers. Every prime number has two factors: one and the number itself.
