If that's 12 and 25, they have no common prime factors, so the GCF is 1.

73 and 89 are prime numbers what is the highest common factor?
3 Is the highest common factor because the last digit of both the numbers are divisible by 3.
How can you tell whether the numbers are relatively prime?
Two numbers are relatively prime if they have no common factor other than 1. Equivalently, if their highest common factor is 1.
What are special prime numbers?
All prime numbers are special numbers because they help us to find the lowest common multiple of numbers and their highest common factor.
Why is it important to know a prime number?
The knowledge of prime numbers is useful when finding the lowest common multiple or the highest common factor of two or more numbers.
Which are the prime numbers with 1 as the common factor?
All prime numbers have a common factor of 1.
What is the highest common factor of 7 and 19?
It is 1 because 7 and 19 are prime numbers
What is a common prime factor?
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
What is the highest common facteor of 48 and 36?
To find the highest common factor of two numbers you first have to split these numbers into their prime factors. In this case, 48 and 36 can be split up as follows: 48 = 2x2x2x2x3 36 = 2x2x3x3 The next step is to identify common prime factors. In this case, both numbers have two 2s as prime factors, and one 3. To find the highest common factor, you multiply these together: 2x2x3 = 12 Thus 12 is the highest common factor of 48 and 36.
What is the highest common factor of 23 and 43?
Since both 23 and 43 are prime numbers, their only common factor is 1.
What are the importance of studying the different properties of whole numbers?
To find out the difference between prime numbers and composite numbers because prime numbers are useful in finding the lowest common multiple of numbers or the highest common factor of numbers.
What is the LCM of two numbers that have no common factor greater than 1?
If the HCF (Highest Common Factor) of two numbers is 1, then the two numbers are relatively prime and their LCM is the product of the two numbers.
The highest common factor of 34 and 58?
To find the highest common factor you first need to break the numbers down into their prime factors. In this case 34 and 58 are broken down as follows: 34 = 2x17 58 = 2x29 The next step is to identify any common prime factors. In this case, the only common prime factor is a single 2. Therefore the highest common factor of 34 and 58 is 2.
